I'd love to see a writeup on why they even went with the central storage model at all – I'm sure there were many considerations but it seems as though CashApp was perfectly positioned to become a mainstream Bitcoin wallet with the private keys in the hands of the users.

Users lose their keys all the time. The cost of support calls alone would probably be higher than the cost of developing a cold wallet solution, especially since it sounds like they already had HSMs and the expertise to use them.
