Hmm... 

When the link is point-to-point (such as in cellular systems), every host has to be assigned with a unique prefix. Doing so makes the use of randomized interface identifiers [RFC4941] ineffective from a privacy protection point of view because the host can still be uniquely identified by its prefix.
