Why not just created it within the .tox root directory and be done with it?

I felt there was an idea behind the decision to not have an explicit call to create that directory – maybe that the workdir wouldn't be eagerly created before it's needed (just to hold a subdirectory).

Just because there isn't does not mean we can't add it.

Sure, I'll do that. Would you prefer eagerly creating the workdir with the cache tag, or having the places that create those workdir subdirs ensure the workdir has the cache tag?

Probably this 🤔

It turned out a little trickier like that, since an user could point Tox to a pre-created workdir, which we then certainly do not want to litter with a CACHEDIR.TAG file.

I still didn't write tests for this incarnation, just in case you'd like to take a review look first.

@akx you still plan to finish this or should I close it?

Yeah, it's still under construction – just been busy with work and figuring out how to best test-cover this. Rebased & added a commit that has some WIP tests :)

No worries, but note the CI is still failing 😊

@akx friendly bump here 👍
