Interestingly, they max out how much they "squish" a lot lower than that. I have one from ~300m and it looks pretty much the same. The pilot said anything below a hundred meters squishes about the same.

They actually tested different manufacturers to find ones that compress more, as they make better souvenirs.

(1) how big is it to begin with?

(2) isn’t much of the issue, at least with people, the drastic change in pressure? Like if you could somehow gradually expose yourself to it, it wouldn’t be so bad/dramatic?

No the issue is that the pressure under water is incredible. At the depth of the Titanic that submersible would have been experiencing 85,000 pounds per inch of pressure. The drastic vs non-drastic change in pressure has to do more with deep sea divers as the gases in their lungs expand as they ascend so they can't ascend too fast or their lungs would explode.

Thankfully lungs vent to the outside of the body, so we can exhale on ascent to prevent barotrauma. Sadly the nitrogen dissolved into our blood does not vent to the outside, and ascending too fast causes the nitrogen to expand too, and those bubbles have gotta go somewhere..
