I feel like people making new VCSes should just re-use GIT storage/network layer and innovate on top of that. Git storage is flexible enough for that, and that way you can just.... use it on existing repos with very easy migration path for both workflows (CI/CD never need to care about what frontend you use) and users
The bottleneck with git is actually the on-the-fly packfile generation. The server has to burn CPU calculating deltas for every clone. For a distributed system it seems much better to use a simple content-addressable store where you just serve static blobs.
Git storage is just a merkle tree. It's a technology that's been around forever and was simultaneously chosen by more than one vcs technology around the same time. It's incredibly effective so it makes sense that it would get used.
