Unfortunately, forcing the return type to be a Path when it previously was a str is a BC-breaking change. It doesn't really matter for _decompress because it's private (leading underscore), but it's an issue here with extract_archive which is technically public.
(Side note: we didn't intend for any of the stuff in datasets/utils.py to ever be public, but that's another story).
We have 2 options here:
- always return a
str. This is sub-ideal but simpler. And since we never intended those utils to be public anyway, it's kinda OK - we should deprecate them and make them private eventually, but that's for another day. - always return the same type as
from_path. This is the best UX, and requires a bit more logic.

Great point. I have done the second option (though technically speaking that also changes behavior from the public API).
