Possible that SN15 will be the first SN to be designed for a landing cradle. The new Superheavies are already designed to land in a cradle now being built at Boca Chica.

It's rocket science - there are limits to multistage engines that make integrated landing gear on heavy hulls impractical on Earth (as we have seen). Cradles likely won't be required on the Moon or Mars.

Migrating to aerospike engines might make large SSTO spaceships with integrated landing gear practical on Earth. No such engine has ever made it to production without being cancelled for budgetary reasons.

The basic multistage engine design was developed during the Cold War at colossal expense, so it seems we are stuck with cradles for now.
