why? sounds like a plan to me.

Would likely end up with more flotation than what it had in the first

My experience with expanding foam was sealing around a basement door: the
stuff expanded enough to bend the wooden door frame. One might want to
use
caution in filling a compartment where the stuff could get wedged in and
(maybe?) crack something.

Yep. That's why.
