++ I actually proposed just that at the mid-cycle in a ML thread a 
couple weeks ago -- though for the life of me I can't remember the exact 
topic of the ML thread so I can't link to it :)

Well, as one of the folks who said that the mindset of folks doing 
stable branch maintenance/approvals is different from that of folks 
working on master...

I don't disagree that stable fixes/backports are important. I just am 
being realistic in saying that, for me personally, stable branches are 
not interesting to me (I don't actually equate stabilization efforts 
with the stable branches) and therefore I don't want to commit to doing 
stable branch reviews (nor do I want to be asked to do those reviews). 
Call it selfish; I just call it being honest about where my priorities 
and desires lie.

All the best,
