Is this the best bet or the one below?

do you really find that this helps? consider this very contrived but 
representative of more complex scenerios example P == parent, A == artifact, 
W == webapp or other assembly

P2 :: A1
P1 :: A2
P2 :: A3
P2 :: W1

A2 -> A1
A3 -> A2

W1 -> A3, A2

If P2 is has a "significant" change in verssion how do you know that you have 
an inconsistent build when you build W1? If you use the "right"  solution - 
as above - then you can actually get the ability with version ranges to have 
maven error when trying to build W1 if A2 and A3 are inconsistence in their 
resolution tree and potentially class incompatible.
