Big Sur is noticeably not compatible with computers that old too.

This the sad, unfortunate, problem though. As time goes on older computers get less capable, they fin d it hard to keep up wth their modern counterparts. They sometimes even seem to lack the chipsets to be able to host the new features/refinements.

That's always the problem if you want to continue making steps towards the future and continue improving things. Even if they did make the new software & OSes compatible, the computers joust wouldn't be able to cope with the extra CPU load. You don't get something for nothing, every new advancement is another demand on the CPU/co-processor.

Apple & Waves won't be the only devs discontinuing support, you'll start to see it more widespread, including Windows platforms.
