the two RS RFCs are split: one is a specification of what BGP must do,
and the other is a recommendation on operational issues.  Glossing over
the fact that IXP operators have not been inserting the rsasn since the
mid 1990s and that the RFCs are dated 2016, the document that IXPs need
to use is the operations doc: rfc7948, which says that RSs should be
operated in compliance with all the bits of rfc7454 that talk about
filtering. Stopping routing leaks is the aim of the game here.

Job, seriously, if you have helpful or useful comments to make, then
please make them.
