That Python app is a popular demo for Cosmopolitan. It's what I would have chosen for that demo, too! It's handy because it outputs a little bit of information about the current architecture on the first line when you start the shell.
Is that an embedded device with a small address space? APE used to require a 47bit address space. The release I published today fixes that. Maybe give it another try?
No, it's a server with 256GB of RAM, but indeed the kernel config has CONFIG_ARM64_VA_BITS_48=y (and 52 for userspace). I have since moved away from this kernel, I'll see if I find the time to boot it again to test the latest memory map manager.
Edit: I tried booting it, the issue is still present, I updated the github issue.
Looks like there is both an ARM and x86 version according to the docs. Probably need two different binaries, but you still get cross-OS for each architecture.

Kind of. It can be read as a single binary, some supported systems will do that. In others, the executable is first parsed as a shell script. There's definitely more to it than a single binary.

Reminds me of a cool tool I once used, uudecode.com, which was a DOS binary that only used 7-bit characters and could decode uuencoded (base64 predecessor) files. Was useful for getting attachments through e-mail in the face of all kinds of filters.
