If you are suggesting that putting a git repo behind it would be an improvement, I'd question that. git is line-based, most freeform notes are sentence or paragraph based. In coding, line length is part of the UX of working in the code, so git works great. Not true for note-taking, where the line length of the data storage is not necessarily tied to the UX of working in the notes.
So I guess the answer is a solid "No" from me. I don't want to risk deteriorating my UX just to solve what is really a back-end data storage concern that I, as the user, should not have to give a crap about, and which doesn't seem to be broken in any meaningful way.
Actually not obsidian, but any note viewer like app. You put files in Google Drive or git repo for that matter.
For that matter, I guess I don't use Obsidian sync, so how does Obsidian present merges that may need manual input?
