1. Move it from "reserved" to "unallocated unicast" (IETF action)
2. Wait 10 years
3. Now that nearly all equipment that didn't treat it as
yet-to-be-allocated unicast has cycled out of use, argue about what to
allocate the addresses to for best effect.

Similar plan for 0/8, 255/8 and 127/8-127.0/16:

1. Move from their existing status to "deprecated former use;
unallocated unicast."
2. Wait 10 years.
3. Now that most equipment that didn't treat it as yet-to-be-allocated
unicast has cycled out of use, argue about what to allocate the
addresses to.

Bottom line though is that the IETF has to act before anyone else
reasonably can.
