I agree that it's simpler for the maintainers. This is good, and the 
only sane solution IMHO. Versioning is hard: why make it harder?

I don't think it blocks unrestrained development in new branchers: how?

Oh yeah, the policy.

;)

Yeah. I think the debug-mode MT fixes are fine and stand behind your 
work: that should be in 4.2.0 IMHO. Same for the rest of the added symbols.

Of course I am willing to share responsibility.... merely stating my 
opinion on the current state.

I'm not necessarily suggesting this as a future, blanket policy. Or even 
that there is any blanket policy at the moment! Or, should be.

Ah. Serves me right to spread confusion when I, now corrected, say: 
D'accordo?

Thanks for this: quite informative.
