Since there are already different options for the front and back cameras, being able to select different frame rates/resolutions for the wide and ultrawide lenses would not be THAT confusing. But for now I think it's best to default to 30fps.
Pro mode not having the ultra-wide is very confusing, since it is actually using less of the phone's processing. It is very annoying not to have on the option since pro mode allows to compensate for the phone's default overexposure without sliding the EV down EVERY TIME and it seems to reduce the oversharpening and other post-processing. Perhaps the wide lens can't support some of Pro modes functions like saving in RAW, but a lot of the very basic things like setting a shutter speed are something I would expect in any modern camera. They should add the lens in to pro mode and lock off any functions that don't work, maybe a little toast notification the first time you switch lenses in that mode to say so.
As an aside, no video in pro mode! Can't lock exposure for videos or lock the shutter to 1/50, so it'll look like phone video no matter what you do.
