Wading in here because I think it's an interesting subject! I've chatted to Dan from Beastmaker about this in the past - regardless of whether you think a hold should be used for 25 years, currently they are not and large volumes of climbing holds and volumes from commercial walls are making it into landfill at an unfortunate pace.
The folks at Beastmaker have been experimenting with sealing wooden holds so that they can be properly washed without ruining the wood - I am not aware as to the status of these experiments, if I recall, the bolt hole or screw holes was the consistent point of failure.
I'm also not sure that Ghold hold sole claim to the 'first recycled holds' thing as Greenholds (https://www.greenholds.eu/) have been doing it at least for a while. Honourable mention to Contact Holds who have been offering a retexturing service for macros for a few years as well. At the ABC conference in 2022 they had this neat offering where climbing wall owners could bring in a macro or hold and they'd fix it up brand new by the next day of the conference. There are different challenges between PU, fiberglass, wood, polyester, and the 'modern style' of setting has moved away from more hard wearing polyester holds to larger more eye-catching PU and fiberglass creations which generally last much less.
I guess I'd draw a comparison to resoling shoes. Some people still climb in shoes they first wore 25 years ago and don't care they're tatty, they do the job. Others burn through pairs quickly and will always be going for the next shiny new thing. Others just want a pair that does the job well and are happy to save some cash and some carbon on a resole job.
This kind of innovation, while not directly relevant to walls and woody lovers (myself included) who are happy to climb on the same holds for years and years, it does meet the needs of the market as things currently stands. There may be room for a broader discussion on whether the trend of constant resets and inflow of new holds can be met in other ways (hold rotation between centres? I saw that 'no tex' holds are in the comp circuit now, maybe we can embrace the polish..?).
I've spoken to other NGBs about their issues with waste and while we're relatively lucky by some standards (a not-to-be-named elite sports organisation told me they shredded hundreds of thousands of pieces of sport clothing at all participation levels due to a change of sponsor, as a contractual obligation), I think it's cool that people are racking their brains to solve these problems or at least partially address them!
