Disagree.  There are lots of ways for constructing commands and
arguments for shells that don't work via shell-command.  Take M-x shell
RET alone and its TAB completion.  Or the TAB completion for commands
like M-x grep.  Or the operation of Tramp.

To pass to some command executing a shell in its bowels.

The problem of "posix-shell-command" is that POSIX shells don't fall
from the tree.  It is something outside of the power of Emacs to provide
or guarantee.
