It’s not related to pipes. I’ve written a shell that has typed pipes and variables handle whitespace correctly. Those two are distinctly separate concerns. It just so happens that many modern shells solve both those problems but it doesn’t mean they’re related.
The problem is both Windows and POSIX passes parameters as a string. So unless you’re never planning on interfacing with any external executables, you still need to convert that variable to a string. That’s where the concern is, not whether pipes are typed.
