Yes, I am considering using something like https://pkg.go.dev/context for this very purpose, though I need to read a bit more into it first.

I wanted to build something fun, I did not check for existing implementations on purpose. I ended up putting more effort than I originally expected into this and now it's starting to look like it could be actually useful, almost by accident.
