George,

The main reason for this was to avoid leaking PE loopback addresses across areas. This reduces the state maintained in the IGP.

I still believe that this won't drastically reduce state or processing.
One of the points in support of this was reduction of compute time for
dijkstas.  Much of this could be gotten by noting what prefixes are
advertised by the set of ABRs and caching the result of just one.  (If
implementations aren't already doing this).

I remain unenthusiastic.
