Comment (by eborisch@…):

 I've added a new .diff file that includes renaming +mpich2 variants to
 +mpich and adding a new (empty) +mpich2 variant that requires +mpich. If
 there are no new concerns raised, I'll be committing it next week. The
 +mpich2 variants could be removed eventually as they exist solely to ease
 upgrades.
