My first wing was an F-one Strike, 7m. I used it all the time and it got pretty floppy.
I mentioned it to a local sail maker/wingfoiler, Aaron, who said he could try to take a bit out. He did it so neatly and it definately helped. Cost v reasonable. Worth thinking about before you retire the old gear. Contact Aaron at 0481 860 999. His modification looks like it was always that way. Caloundra based.
I did a take up on the canopy of an old wing last year and it breathed a little more life into it. Between that and running higher pressure till the LE fails catastrophically you can def squeeze 6 more months of performance out of a tired old ding.
i just pumped it up and used sail tape to make a fold that takes up some canopy in the back half and kind of tightened things back up. Then I sewed it on my mom's sewing machine. Worked great.

Sounds great. Can you share a picture?
There was a thread a while back where a sailmaker here on the board proved that the sailcloth is not the problem, it's the dacron / frame stretching and allowing the draft to shift rearward.
That all said though the result is the sailcloth gets baggy regardless of how it happens.
I did have a V1 3.5 Strike that appeared to be sewn incorrectly and one side was baggy and flapped a lot. I gave it to a sailmaker who put about an 8" cut perpendicular to the TE and "took it in" a bit, taped and sewed it. No Idea how much but maybe it wasn't enough. The TE still flutters and flaps on that side

There are some interesting perspectives in that thread, though unfortunately SeaBreeze says it's too old to resurrect for a response, so I thought I'd share an alternative take here: what if, instead of tightening the sailcloth, you support the frame, possibly with some lightweight battens along the trailing edge of the sailcloth (i.e. perpendicular to how most wings are battened), pressing outward between the centre strut and wing tips?
This way, if the issue is indeed with the frame structure being pulled in (as opposed to the sailcloth bagging) over time, you support the frame and keep the sailcloth taut.
Of course, if the issue is instead with the sailcloth stretching, then the transverse battens will exacerbate the issue, but at least it's one way to find out the true cause.
So the question then is: how would adding a batten along the trailing edge affect wing performance?
Extra battens definitely help with flutter. I've stuck some on using Dacron repair tape, very easy and effective. I used some thin carbon strip about 5mm wide and 0.5mm thick. I put some tension on as I stuck them on, that seems to help too.

You're fundamentally correct. Frames stretch out with lighter dacron frames, from the original thread wings have developed a lot. So much so that between v2 - v4 wings I've noticed that fundamental longevity has increased.
My v2 strikes were clapped out at 8 months of use, my v4's perform as if 1 month old, with the same. Brands have learnt a lot over the years. Tapered strength and different weight cloth has been the key here.
We've mucked about with battens in canopy, in frame and so forth. This works and adds performance for blasting, but wave riding and freestyle it's a bit ****.
If you replaced the frame with something spectacular, or just in the T-junction with Tyra-ply/ 3Di raw I'd argue you've the best wing available. Problem is, we've still got 5-10 generations of wings before north/ someone else will release this - lots of money to be made in the meantime.
Anyway - add battens or do whatever you can to add longevity it's all fun and games to learn!
Interesting posts on this. My latest cloud 9 wings are definitely tighter and there's a feeling of being more directly connected to the wind. Time will tell how they handle use over time. I suspect better, consistent with posts here about improvements in the technology.
Having said that, Aaron is a knowledgeable sail maker and the modest changes he made definitely had a positive impact on my older v2 F-one Strike. As such I think it was worth the modest spend.
I've never added battens. I'm thinking about a new sew batten instal with some double sided foam mounting tape between the canopy and the batter to keep the hard spots on the batten from popping a hole in the canopy and then some stick back over the batten/mounting tape to clean up the top.
