To me jj is an ok porcelain for git, but I find it worse than magit. Sure, it has some tricks under their sleves for merging, but I just don't run into weird merges and never needed more advanced commands like rerere.

What I'd would expect of the next vcs is to go beyond vcs of the files, but of the environment so works on my machine™ and configuring your git-hooks and CI becomes a thing of the past.

Do we need an LSP-like abstraction for environments and build systems instead of yet another definitive build system? IDK, my solution so far is sticking to nix, x86_64, and ignoring Windows and Mac, which is obviously not good enough for like 90%+ of devs.
