Per RFC 3501 (page 63):

       PERMANENTFLAGS

          Followed by a parenthesized list of flags, indicates which of
          the known flags the client can change permanently.  Any flags
          that are in the FLAGS untagged response, but not the
          PERMANENTFLAGS list, can not be set permanently.  If the client
          attempts to STORE a flag that is not in the PERMANENTFLAGS
          list, the server will either ignore the change or store the
          state change for the remainder of the current session only.
          The PERMANENTFLAGS list can also include the special flag \*,
          which indicates that it is possible to create new keywords by
          attempting to store those flags in the mailbox.


It appears 2.3.x supports '\*':
