It depends on the address format.  Not all format prefixes require the
64-bit interface ID field.

Agreed that, in the global aggregatable format, subnet prefixes longer
than /64 create problems.

However, implementations should be kept unaware of the magic /64 boundary,
as much as possible.  (Obviously, the piece of code that does stateless
autoconfig has to know about it, but certainly not any routing code.)
