RFC 3315 section 22.5:

   An IA_TA option does not include values for T1 and T2.  A client MAY
   request that the lifetimes on temporary addresses be extended by
   including the addresses in a IA_TA option sent in a Renew or Rebind
   message to a server.  For example, a client would request an
   extension on the lifetime of a temporary address to allow an
   application to continue to use an established TCP connection.


But I'm not convinced temporary addresses fits that use case.

In any case, there are existing client implementations of IA_TA (for
example ISC dhclient and dibbler) and RFC7721 stable IIDs (for example
Linux kernel and NetworkManager).
