Fortunately I do not have to rely only on my memory :)

I guess that's the point where we break. I agree that moving from 2 to 3 signals
major change. At the same time once some project moves to double digits versions
my experience is that I am no more keeping track which version is which unless
I have special interest in some bug etc.

So if we keep the current scheme we can spare +1.0 switches to unusual transitions
or symbolic moves. If we move to the proposed scheme we'll lose this option in
some 15 years.
