What do you mean by "deprecate the /64 onlink prefix"?

Are you referring to this part of
draft-liu-bonica-v6ops-dhcpv6-slaac-problem?

   [...] But when
   SLAAC-configured, and A changed from 1 to 0, the behaviors varied,
   some deprecated SLAAC while some ignored the RA messages.

On re-reading it now, the draft text (specifically "deprecated SLAAC")
is not very clear either, but at least it's clear to me that this is
about address configuration, not about on/off link.
