The "+0.1" and "+1.0" are not quantities, just ordered uniquifiers.
Unless we break backwards compatibility or essentially establish a new
language like we did with 4.0 and 5.0, I see no reason to skip minor
version numbers.  To me, version increments are +0.0.1, +0.1, or +1;
there's not a whole lot of call for jumping by 2s or 5s or whatever.
If we do want an intermediate state, just add another digit in the
middle.
