I won't debate the swim/avoid issue - that's Wayne's family prerogative.

I always thought that a pool bottom can't support a point load like those footings. I'm guessing Wayne thought about that.

Good idea on the trap door to gain access to drain water.

It looks good, but I would have used Trex or similar material for the deck. Zero splinters, zero maintenance. And you can sell it when you are ready to go back to the pool.
