I have not a strong opinion about the opportunity of supporting just
one MPI flavor or all available ones. In current stable all flavors are
supported and I suppose users would be not so happy to see them
disappearing in squeeze. For sure, current multi-flavor building would
require a decent common infrastructure, instead of different hacks
spreaded around all interested packages. If you MPI maintainers are
not going to support multi-flavors I would prefer to drop that
in squeeze+1.

That said, a patch for add mpi-defaults to current support 
is of course welcome.
