Since there was no announcement and I have not seen anyone point this out:
There has been an option for "Background Removal" in the Generator Queue/Feed options for a few days now. It's Members only too, and I'm not spending money to assess how well it works when I don't even have a need for it. Maybe it's useful to someone though.
I think the most interesting fact about it is that this is, to my knowledge, the first Generator feature behind a paywall. All other Member perks so far have been either for convenience or promotion. Make of that what you will.
