Yes, but there are other problems if you subnet to the right of /64 (autoconfiguration for example).
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.) Steve
