RFC 4941 does require public addresses:

   1. The text explicitly says in several places that privacy addresses are
   "in addition to" public addresses.
   2. If you don't have a public address, critical parts of the
   specification, such as how to extend the lifetime of privacy addresses when
   receiving an RA, are undefined. An example is the text that says, in
   effect, "when an RA would extend the lifetime of a public address, then
   also extend the lifetime of temporary addresses".

If we want to reclassify it as is, we'll have to accept that the resulting
Internet standard document will only a) define the behaviour for privacy
addresses with a public address, b) say that privacy addresses should be
depreferred by default.
