Re: [GROW] Input on AS Prepend for draft-idr-rpd-15.txt

[Speaking as an individual contributor.]

Prepending has been around for ages and it's well understood at this point in how it behaves.

An older version of the grow prepending document was nicely clear as to why excess prepending was problematic.  From that perspective, the document was useful.  More recent versions of the document have muddied its clarity.

I don't find it needful that BGP protocol documents reference this document in particular.

This begins a 2 week call for requested input on the beneficial use of AS Prepend. draft-ietf-grow-as-path-prepending-05.txt indicates there is a risk in excessive prepending. In section 5, this draft suggests there is no need to prepend more than 5 ASN in an AS Pathway by a single AS.  Is this recommendation firm or likely to change?  Should a comment be added to the draft-ietf-rpd-15.txt security section to point to the draft-ietf-grow-as-path-prepending-05.txt draft?
