hi tim,

(  omg!  someone is alive in this wg!  :)

within the trust boundary, one tends to want to manage complex services
on fewer devices.  route reflection is a poster child; the clients
have a restricted number of peers and a minimized consistent view.  so
it is what we used in the text.

   Within a routing trust boundary, e.g. an operator's Point of Presence
   (PoP), it may not be desirable or necessary for all routers to
   perform Origin Validation using the Resource Public Key
   Infrastructure (RPKI) per [RFC6811].  A good example is route
   reflectors (see [RFC4456]).

a pop may have a few dozen routers.  no need to run rpki-rtr and full
validation on them all.

one can do it with policy, no need for a whole rpki-rtr client and
