I have not ever studied POSIX academically (curricularly) but:

> a small set of minimalistic APIs that remain stable over time

but from what I've gathered (over years, by 'osmosis'). Isn't this the essential idea behind POSIX?

Yes, but POSIX doesn't provide APIs for graphics or audio, for example, even though these things are necessary to build a lot of end-user software.
