The problems here are not exactly flakes going too slow or too fast. It is that the historical developer of nix, who was also behind flakes, moved to create a company called Determinate Systems. And this company keep pushing out products that are "ways to fix all kind of problems with nix and flakes". Except they are done in secret then announced, while the rest of the community is trying to actually make the underlying stuff just work. It is a bit like the guy built a half finished stuff, good enough for him, leave it in this state, then keep coming back with "solutions" that are not in nix themselves. And let everyone else clean his stuff. Ofc the other way to look at it is that they are the only one having results and really fixing things. But I am on the side of all the other maintainers that keep having to clean up the mess.
