We did this for a long time for our CMS - although we did simulate a filesystem structure. We also set up a git-like system to store versioning information and set up WebDav to mount it all and allow direct source code editing. It worked pretty well for years.

We eventually stopped because we were relying much more on external tools (eg npm, webpack) which had all sort of issues over webdav mounts. Maintaining all this code management infrastructure in parallel wasn't worth it in the end, and we moved the code back to disk, switched to git, etc.

And photoshop silently ignoring webdav I/O errors when saving designs didn't help either.

You already have tagging by type on the filesystem - the file extension. That allows you to limit file searches. Add extra metadata to extensions if the same extensions have different roles (.backend.ts, .frontend.ts, .html.template, .text.template)

These days I prefer to structure for easy removal of code - everything for eg. a widget (frontend, backend, css) goes into a folder and I only need to remove that folder when the widget is retired, and linting/validation will show me the few remaining path references I need to cleanup.
