This is why there can't be 'one mesh to rule them all' to use a Tolkien paraphrase.  One geometry and rigging can't be both a human and, say, a dog.  Not possible.  You can alter the rigging and geometry (via morphs) to create a dog from a human but that is quite a bit of alteration.

Morphology here, in the biological sense, dictates that more differences bely the two than simple surface morph changes or simple structural changes.  V4 to A4 isn't a big stretch (this is basically an anime version of V4, aye?).  But V4 to M4 or Luke4 won't cut it solely as a morph.  So the 'set up differently' involves structural changes - that is, rigging changes.  That completely separates ubiquity of form from practice.  This means, in essense, "You have V4 which takes V4 things and M4 which takes M4 things except maybe textures."  This is no different from the previous enterprise except that like forms might be more tightly compatible (females to females, males to males).  Good/bad, we'll need to see how this plays out.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
