This looks great so far, thank you @simonhammes!

I think long term pyinfra should be moving towards inventory functions as the default to avoid the weird "list or tuple" thing for hosts/groups.

There's also potential for a DSL kind of inventory, but that's a future problem :)

That seems like a wise decision imho.
Should I even bother to fix the generator support (see the open thread in this PR)? Or just update the documentation?

EDIT: I'll also add some tests.

Let's just update the docs, would rather not increase complexity of the current situation!

Change looks great so far, tests would tie this up nicely!

Thanks for the feedback, I have updated the docs.

Thank you! I agree, I'll add some tests.

Let me know if you had something else in mind re: tests 😅

Did not know where to put this - maybe into deploy/inventories?
