"It was originally my understanding that if you ran Windows 7 joined to a domain, then GWX would ignore you, however this seems not to be the case anymore, as I've had to play whack-a-mole on a number of my domain member desktops recently."
I don't think that's ever been the case, it's only people running Enterprise edition that can't receive it. Pro users (certainly retail versions of Pro) can get it even if they're joined to a domain, though obviously if they're in a domain environment there's a better chance they get their updates centrally managed, and the admins have already excluded the offending update from being applied.
