A good point -- we didnt discuss when we want to do the next 'big API change
window' (even if that might be somewhat off). We should do that soonish, so we
can make qualified decisions on that(*). I fear otherwise we might drown
ourselves in bikesheds on case-by-case decisions.

I suggest to bring this on the ESC, but maybe next week -- its not superurgent,
everyone is hibernating from the release and those who are not are at GUADEC ;) 

Best,

Bjoern

(*) e.g. is can a bugfix wait until then or does it have to be
done/workarounded _somehow_ now.
