I just wanted to chime in to cheer you on, I've been following this Rust-based `git-subtree` idea with interest. You may know it already, Git for Windows is shipping `git subtree` with its installers for ages, and given the abysmal performance characteristics of shell-based Git commands on Windows, it would be really good to replace the shell-scripted version with the Rust version (also to ensure proper error handling, which is hard to make comprehensive in Unix shell scripts). Thank you for pushing this forward! Ciao, Johannes
