I think you missed the main reason that the MPICH folks, at least,
implemented wrappers for the compilers which is :-

0. Give a consistent command for compiling MPI codes no matter which
   platform you are currently working on.

There is a class of people (particularly those at the "National Labs")
who have accounts on many different machines, and support code on lots
of them. To these people having a common way of asking to compile
an MPI code is a big win. For most of us, who only have one machine to
worry about, this is less important, of course.
