There are some advantages to the pour-in foam: (1) It adds rigidity to the hull, (2) it adds a degree of puncture-proofing; the stuff is very adhesive, and if something punctures the bottom the foam may keep the water out. (3) It thoroughly fills the irregular space, leaving no room for water.
You've already identified the disadvantages. I thought I was being careful by pouring in a little at a time then letting it expand before I added some more. I still overdid the final shot. I was pouring it in through a hole sawed in the plywood (on my boat) bunk deck. I found myself frantically boring multiple holes with a holesaw to relieve the pressure, as the deck bowed upwards and made splintering sounds. I later had to remove the plywood when rainwater rotted it out. I sailed the boat for a year or so with only the foam in the forward cabin; the boat was still structurally stiff with just the foam and no deck. Later I shaved the foam off flat and installed a new plywood deck over it.
I'm still glad to have the foam in there.
My apologies to those who have heard this story before.
