In principle, I agree, of course: at this point the mainline is not 
supposed to care about this kind of issues!
On the other hand, however, Benjamin said at some point, that he would 
rather prefer dealing with just 2 branches (main and release), not three 
or more!

As you said, probably the best solution for everyone is branching as 
soon as possible!

Ciao, Paolo.
