I personally have a "sandbox" directory that I put one-off and prototype projects in. My rule is that git repos never go in any dir there. I can (and do) go in almost any time and rm anything older than 12 months.

In your case, I guess one thing you could do is have one git repo containing you most commonly-used dependencies and put your sub-projects as directories beneath that? Or even keep a branch for each sub-project?

One thing about `uv` is that dependency resolution is very fast, so updating your venv to switch between "projects" is probably no big deal.
