I know it's consistent with respect to reference counting semantics, but it might be harder for new users to find when searching the docs. I have no data either way. I recall discussing years ago that having paired MatGetSubMatrix/MatRestoreSubMatrix would simplify bookkeeping in PCFieldSplit and some common user code. If the name is changed, it's easy to support the deprecated name from C.
