It appears that RFC 7217 does not actually demand a 64 bit interface
identifier. One could therefore do a non-64 bit RFC 7217 SLAAC on operating
systems that support that.
"We note that [RFC4291] requires that the Interface IDs of all
unicast addresses (except those that start with the binary
value 000) be 64 bits long. However, the method discussed in
this document could be employed for generating Interface IDs
of any arbitrary length, albeit at the expense of reduced
entropy (when employing Interface IDs smaller than 64 bits)."
