FCP-2 and RRQ

In FCP-2 version 4, section 12.5.2, as part of ABTS processing it
specifies:

"Upon transmission of any of the above responses, the SCSI Target may
reclaim any resources associated with the designated Exchange after
R_A_TOV SEQ_QUAL has elapsed or a Reinstate Recover Qualifier (RRQ)
extended link service request has been received."

No where in FC-PH* does it say that resources can be reclaimed by the
ABTS recipient without an RRQ.  Is this new behavior intended (if so,
it should be defined in FC-FS).

And if this new ABTS behavior is intended, why is there any need to
send RRQ at all?  The ABTS initiator will wait R_A_TOV SEQ_QUAL before
it sends the RRQ, and the ABTS recipient will automatically reclaim
the resources after R_A_TOV, so it would seem that RRQ is not
necessary.

Comments?
