People have started joking that Krithalith might be able to figure out moat door skip RTA. He has already managed to do an IL of BitFS with a PU strategy, so I'm starting to think that what is currently only a joke might (eventually) stop seeming so much like one.
On the other hand, as much as I am always optimistic that speedrunners will eventually figure even really crazy things out, Moat Door Skip is really out there.
For this to resolve YES, it doesn't necessarily need to be performed in a full 1 Key Any% run, just performed at all. I think I'm inclined to say that a savestate prior to starting the BLJ in the vanish cap stage is allowed, but not one between the BLJ and the PU? But I mostly expect that someone will go for any% WR using it if it starts looking viable at all.
