Yeah, I'd echo a bunch of what Vladimir said, selectors are useful for different mail streams from the same domain, and we've played with using it for reputation (as a tuple with domain). That said, we don't want to discourage rotation, especially not anything crazy like requiring senders to ramp a new selector/key, doing something crazy like using both keys at the same time and slowly replacing one with the other.
Unfortunately, most folks don't seem to rotate very often (and Google as a sender isn't doing this well either), so we need to be careful. As long as it's a weak signal combined with others, it's probably fine. And, as always as a disclaimer, anything's fair game to change with no notice when we're staring down large new spammer campaigns.
