Reasonable argument. But, volatility is a conservative choice;
readonly-ness is an optimistic choice.
But the structure and scalar attributes that are moved are also an
optimistic choice.
It's certainly not safe if the new MEM is bigger than the old one.
Sure, but when would you do that? I can't think of any time that such
a thing would be done.
