This is an optional accessory.

A /63 prefix is beneficial for a Mobile Router, or 'IoT Router', for
local area tethering, or for in-vehicle networks.  It gets a /63 from
the ISP and makes two /64s out of it.  One for its WiFi interface and
one for its Ethernet interface.

If it only gets a /64 then it cant make other /64s out of it and it
can't route.
