At least Juniper boxes use interface names such as fe-0/0/1 (that is
they include forward slashes) and my understanding is that those names
won't fit into IPvFuture:

  IPvFuture  = "v" 1*HEXDIG "." 1*( unreserved / sub-delims / ":" )

  unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

  sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                    / "*" / "+" / "," / ";" / "="

RFC 4007 does not really restrict the characters allowed in zone
identifiers and hence it seems to me that we can't simply assume zone
identifiers are always consistent with IPvFuture. (But I might as
well be missing something.)
