Some providers have indicated that the route servers would better
serve their needs if: 1) the RSs implemented only a subset of the
policy expressed in the IRR and 2) the RSs could do proxy aggregation.
The configurations of the RSs support both of those requirements
now. The policy language does not yet support this in a "standard"
fashion, but that is being addressed in the RPS working group.
The RA has implemented requirements that providers have when a
provider communicates what is needed. I can't find any messages
from Sean indicating what he would like to express but can't.
The RA team is always willing to work with providers to meet
