Personally I am +1 on "patches welcome" until users start asking for
it (including via list and site managers).  Until I see evidence of
intent to use, I'm not excited about putting the effort into
developing and maintaining it myself.

I wouldn't have a problem with experimenting with enabling
personalization by default in Mailman 3 to get experience with it.

I would oppose it in Mailman 2 at this point in its lifecycle because
throttling of hosted lists is still a FAQ, and (at least
theoretically) multiple recipient transactions can alleviate those
limits.
