One advantage (without looking at the regs so beat me up) is if you are VFR

Just ask the tower for a "Contact approach" instead.

Well that could get involved. You'll have to request and get an IFR
clearance. You'll then have to climb to the MVA to make that clearance
effective. That may or may not allow you to finish your scud run. I
doubt if it will.
