Heh...you beat me to it. Yes, in extreme situations, not only is genocide sanctioned by Starfleet, it's downright policy.
Starfleet will do extreme, almost immoral things when its survival is threatened. In The Pale Moonlight is a perfect example.
Starfleet doesn't believe in orbital bombardment of cities. During the war, they kept reaching to the Dominion for peace. They most likely let the Jem Hadar and their ships return to Gamma Quadrant after the war.
Picard let the Borg go, rather than unleashing a virus that would have destroyed them, under the weak notion that Hugh's individuality would affect the Borg. But it didn't work.
All the evidence says the Federation is just too nice to ever do such a thing, but when it gets desperate or scared, they just might resort to it.
It's a case by case basis. Not always an easy solution depending on who they're dealing with.
With the Borg and the Dominion, I don't think anyone would lose a whole lot of sleep about it, except for Bashir, Picard, Beverly Crusher and some others.
The Dominion was seen attempting genocide at least 4 times already.
