The "parliament cannot bind its successors" principle was absolutely (and deliberately) imported into US law, yes.

It's more general -- no branch of government can bind its own successors. (With the exception of e.g. presidential pardons which cannot be undone)

I think this is generally true? It’d be weird if there were some laws from 30 years ago that nobody wanted, but were not legally allowed to be changed. You’d just change them anyway and nobody would care.

It's generally true precisely because British parliamentary democracy formalised the concept, mind you. Before that, yes, rulers made laws that would perpetually benefit them and their successors.
