Hello,
Sorry to participate in this draft so late, my apologies.
I support the draft and looking forward to have a formal document
addressing as-prepending.
My small comment, maybe a litte bit crazy idea; after reading the
document and going thru the discussion in the mailing list, I wonder if
it good to mention when a transiting AS performs prepending of customer
prefixes and the customer does not want it do be done :-)
Thanks,
Alejandro,

Abstract:
AS Path Prepending provides a tool to manipulate the BGP AS_Path
attribute through prepending multiple entries of an AS. AS Path
Prepending is used to deprioritize a route or alternate path. By
prepending the local ASN multiple times, ASs can make advertised AS
paths appear artificially longer. Excessive AS Path Prepending has
caused routing issues in the Internet. This document provides
guidance with the use of AS Path Prepending, including alternative
solutions, in order to avoid negatively affecting the Internet.
