Note that the above POSIX text is only relevant for the _system_call_.
What POSIX.2 says about the behaviour of the "ln"/"cp" commands is another issue. I agree with you that it would _seem_ like their behaviour is less than desireable, but whether it is a bug is not clear.
LN(1) LN(1)
NAME ln - make links between files
SYNOPSIS ln [options] source [dest] ln [options] source... directory
POSIX options: [-f]
GNU options (shortest form): [-bdfinsvF] [-S backup-suf fix] [-V {numbered,existing,simple}] [--help] [--version] [--]
...
In other words: -b is a GNU extension. There is no POSIX.2 requirement on -b. The same holds for cp.
