Zip support in cpython stdlib has been there forever (I think it might even be from 2.0 times, early ‘00s) but it’s never been very user-friendly or particularly advanced. It’s one of those things like timezone and http, where the implemented API didn’t really come out “right” and there has been some pain ever since. It’s a bit like SSL stuff in JDK: something that should instinctively be very easy just... isn’t.
