Writing it in Python did come up and was decided against, but I don't
recall the reasoning. Could it have been a performance thing?

At pycon I talked with a few people about bugs.python.org/issue19699

The consensus seemed to be that zipimport wants a lot of work, possibly
a rewrite.
I'll have some time to work on this over the next couple of months, but
I want to be working on the right thing. Could the people who were
involved in that conversation remind me of their concerns with
zipimport? What exactly would the goal of a rewrite be?
I believe the participants consisted of Thomas Wouters, Greg Smith, Eric
Snow, Nick Coghlan, and myself. In the end I think the general consensus
for long-term maintenance was to write the minimal amount of code
required that could read zip files and then write all of the
import-related code on top of that. Basically the idea of freezing
zipfile seemed messy since it has a ton of dependencies and baggage that
simply isn't needed to replace zipimport.
Hey, I was there! This is what I recall as well.
I vaguely remember people suggesting writing the minimal zip reading
code in C but I can't remember why since we have I/O access in importlib
through _io and thus it's really just the pulling apart of the zip file
to get at the files to import and thus should be doable in pure Python.
I don't think writing it in Python ever came up. I can't think of a
reason why that wouldn't work. Rose: this seems like a good approach to try.
Eric.
