They had to give that up because it was too slow, I think for IO. Unfortunate.
It's complicated. WSL1 is much faster at accessing the drives mounted in Windows, but much slower at accessing its own emulated drive.
If you have control over where you put your git repo, WSL2 will hit max speed. If you want it shared between OSes, WSL2 will be slower.
It also didn't have working fsync, and corrupted SQLite databases. I think that's more important.
