This proposal covers a subset of the functionality pitched in Controlling the ABI of a declaration; specifically, it supports
func,init,subscript, andvar, but excludes nominal type declarations,typealias,extension, andcase. In addition to limiting the scope, this version of the proposal fills in a lot of details that were left vague at the pitch phase, most importantly the general framework for deciding how we check features for compatibility.Most of this feature has been merged into main behind experimental feature
ABIAttribute, though minor changes that came up while I was editing the proposal are still being implemented in swiftlang/swift#79466. There's also a standard library adoption PR at swiftlang/swift#79937 (I need to rebase this very soon).
