Instead, this version of the proposal leverages those existing methods to inform a more compact API design which has less surface area, and is more future-proof since it obviates the need to design and add another (redundant) set of protocol-oriented pointer APIs later.

Would you mind adding a deallocate method to (nonmutable) UnsafePointer/UnsafeBufferPointer to take care of
There’s simply nothing in the memory model that requires mutable memory for deallocation.
It fits right in with this proposal and hardly seems worth a separate one.
