BTW, not a strong opinion, but I don't think we need to be too conservative about including bugfixes in stable releases. If we have targeted bugfixes that shouldn't be too risky, it's ok to include them.
It depends a bit on where we want to go with these. 1.7.1 and 1.8.1 were fixes for things that arguably shouldn't have made it into 1.7 and 1.8 in the first place. I could see us moving to a scheme where we did more regular bugfix releases though; e.g. 1.9.1 a month after 1.9, and 1.9.2 a month before 1.10. At that point it would probably make sense to try to include a bit more in those releases.
