I don't think the discussion is over the major/minor version structure.
I believe I understand (and heartily defend) the version number structure.

Notwithstanding Roy's intent two years ago, what is abundantly clear is
that the intent does *not* come through in the text, or there wouldn't
be two good-faith interpretations with (I'll venture) comparable
numbers of proponents, each claiming the "preferred" interpretation.

Both sides have made their arguments, and I won't rehash them.  I will
argue that the words in the text should be clarified either to take one
of the positions or to state explicitly that a conforming
implementation can follow either position.  While I find the latter
choice perverse, at least it will avoid finger-pointing by one camp's
saying the other violates the spec.
