What cameras support exposure bracketing with flash (not flash bracketing)

[LongLensPhotography]

I have this with 5D mark III Magic Lantern hack and it is so incredibly useful. Essentially you can bracket in AV mode any way you like but also have flash / strobes on either as ETTL or manual, as you wish. By default it would not allow any bracketing with flash (not to be confused with FEB which is far less useful to me). Another great feature is that it will keep bracketing down all the way in exposure all by itself until it detects no overexposure thus saving a tons of time. Interiors have ridiculous DR (as bad as 25-30 stops) so this helps A LOT, and you just don't have days to do it "Properly" and also face more tripod shifts.

Do any of the other newer high end cameras support similar functionality out of the box? Any make...
