Suresh, I think the general answer to your questions is "historical accident". Matshow was contributed a long time ago, and has been updated only minimally to take into account changes made elsewhere. There was even a suggestion that it might not be needed any more, but I think that it can continue to be useful and is worth updating to be an axes method, etc. This is on my growing mental list of things to do, and is probably one of the easier ones.
