@GitKraken - thank you for the additional information. If moving to classic, the plan sounds reasonable.
This was left unanswered: "Please note that since your snap was added to the store, we have added a number of interfaces including ones for gpg, ssh, personal-files (for accessing dot files) and system-files (for accessing files in, eg, /etc)?. Have you explored these newer interfaces and perhaps using snapctl is-connected <plug> to provide a better UX for manually connected plugs?
This doesn’t address the issue of git hooks though, and there are other snaps like git-cola that were granted classic for this reason."
