SpaceX has absolute massively iterated in every single thing they do, what the heck are you talking about? The Falcon 9 more than doubled it's payload from v1.0 to FT Block 5, and gained first stage landing/reusability through a host of iterative improvements. Starship's development has been all about hardware rich iteration with plans to enable it right down to the basic material level. They've been big on MVPs and then iterating from there.
