I don't want an only-POSIX-compliant OS or userland, because POSIX is not a good standard. POSIX is "let's standardize the lowest common denominator across popular commercial Unices". Almost everything in the GNU coreutils is there for a decent reason - in many instances because of severe problems with the POSIX spec (just think about all the POSIX tools handling record-shaped data, but not supporting NUL separated records) or because it's just handy to have.
