There are already various ways in which mercurial or perforce are better than git, and big companies like Google and Meta have hacked on the systems they started with so much that one can hardly say they’re still perforce/hg. There can be disadvantages there but it seems obvious to me that better systems are possible. It feels to me like the real question is whether GitHub is the endgame.
