And even then it's not that simple.

I'd interpret it as being able to do `USER=notme inc'.

Should we simplify the code to demand $LOGNAME exists and use that?
POSIX, he say

    LOGNAME
        The system shall initialize this variable at the time of login
        to be the user's login name.  See <pwd.h>.  For a value of
        LOGNAME to be portable across implementations of POSIX.1-2017,
        the value should be composed of characters from the portable
        filename character set.
