See, I'm not sure that I agree that this discipline isn't meant to use the Social Maneuvering rules.
When he wills it, all eyes fall on the vampire and nobody cares what he’s doing. For the rest of the scene, he suffers no penalties to Social rolls from his actions or appearance — even if he’s just beaten another man to death or waved a gun in a crowded nightclub. Given a chance, he can talk his way out of minor criminal offenses and almost any social faux pas. As the center of attention, he adds his Majesty dots to any Presence rolls when talking to people around him. This bonus only applies when talking to people normally, not to other uses of Majesty.
That part seems to pretty clearly indicate that it's used for regular social rolls. It doesn't bypass them. If anything, it reinforces that they need to be used.
But there's also Blood Bonds, too, not just the Majesty discipline Take a look at the very top tier, which mechanically provides:
When taking a Social maneuver against her thrall, the regnant’s impression is always considered perfect (see p. 174). As well, she gains a +3 die penalty on any Social action or Discipline roll against the thrall.
That is absolutely doors. It straight up says social maneuvering, and gives an indication of Impression, which there's no other reason for tracking than the SM rules.
So while I think vampires are pretty awesome, I'm not sure that they work so well on MU's under the new system, because a lot of their powers that aren't 'kill you dead motherfucker' fall under the 'Now Newly Optional' guidelines that OP was short-sighted enough to put in the books without really checking to see what other systems it affects.
If a MU makes it clear that SM is being used, then it's not an issue. If they say it's not, then it's a fairly substantial issue. I've seen many a Daeva bellyaching that they feel like they're getting shafted.
