If that were the case, then to be consistent you'd need to change how list processing is handled system wide. Should {1,2}+{3,4,5} return {4,6} or error?

There is a third option- cycle the contents of the shorter list. The above example would then return { 4, 6, 6}. Some Mathematica commands do this.

Whichever option is chosen, it needs to be consistent and well documented.
