In a future year (I have no bandwidth to explore this now):
I would love to see a pants integration for packaging python apps with beeware/briefcase (a PEX and PyOxidizer competitor). https://beeware.org/briefcase/ (https://github.com/beeware/briefcase)
Two things that makes briefcase a compelling option:
• the target OSes: Mac, Windows, Linux, iPhone/iPad, Android, Web
• beeware/toga python-native + OS-native GUI toolkit: https://beeware.org/toga/ (https://github.com/beeware/toga)
◦ targets the same OSes as briefcase!
