also, the cost of startup for large pex files is becoming painful for us (10s of seconds) in a zip_safe=False world; fwict, leveraging something other than python’s zip support, which is horrendously slow, (maybe a quick python + rust lib) might be a quick win there. the problem would be that this would make pex platform specific, but could be a “use if present” type thing.

we decompress stuff with rust with pants right now
just for unpacking v1 cache artifacts
so pants could possibly make use of this as well or we could rip it from pants either way
pyoxidizer is pretty cool too for import time, or at least the idea of it
