I'm pretty sure some people would assume that it stood for {1,X}, not {0,X}.

That says nothing without an idea of how common such an assumption would be made and an idea of the size of the negative impact making that assumption would entail.

one to X matches makes more sense than zero to X matches in many situations.

It makes sense in some situations, not necessarily many.

It's propably best to force people to make an explicit choice.

It's even better not to break backwards compatibility.
