I've toyed around off and on with FUSE drivers for various purposes, and hiding information like tags and then preserving those tags on save is something you can delegate to your filesystem. The advantage is that tag-hiding now works automagically with ripgrep, your favorite editors, and any other dev tool.

You _are_ limited in that you can only detect edits during interactions with the filesystem, which is strictly less information than you'd have in an editor tracking every keystroke, but a good diffing algorithm still mostly gets the job done.
