Few more counter arguments against expanding identifier length:

1. There is a rejected errata 4406 that wants to do this

2. FreeBSD and probably other *BSD/macOS use those unused 56 bits to
store the link scope_id. And support nonstandard fe80:1::30/64 notation
instead of fe80::30%1/64 to specify the scope.
