Im using helix and currently work in a go-project. The lsp for go actually works quite well, and offers actions like turning an if-block around or modernizing certain code-snippets. So at least in theory it should be possible to implement these features for other languages too, though Im not sure what sort of complex operations modern IDEs offer; i didnt find vscode too impressive when i still used it

You could create a git branch with an unrelated history to store this type of data; either as plaintext, md or something more sophisticated for dedicated tools. The biggest hurdle would probably be to define and agree on a standardized format
