> 1. Backwards compatibility with existing libc. (Maybe pick musl)

Honestly, that ought to be a non-goal. We already know that POSIX often enforces models that we don't want--filesystem permissions and the fork model are two good examples of things that are broken. So why start with "implement POSIX"?

The backwards compatibility isn't a testament for POSIX's merit. Sure, please introduce better, safer paradigms whenever you set standards, but enabling legacy software to run immediately is a great value proposition.

Also, goading legacy maintainers to adopt the newer, safer paradigms is likely more effective if you show them the traction the new platform is gaining

POSIX doesn't mandate fork, that's why it invented posix_spawn.

POSIX != C and from what i understand from the official docs, they already have a (musl derived, even) C library.

The C stdlib is so married to POSIX they may as well be the same thing.

Actually no, go read ISO C and compare it with POSIX expectations.

…on UNIX systems. C is still a thing for other platforms e.g. embedded where POSIX is not a thing.
