Although it did a few other things as well, an attempt at standardizing
parts of this failed:

draft-bonaventure-bgp-redistribution-01

This draft included:
IDRP style DIST_LIST_INCL, DIST_LIST_EXCL
Proxied NO_EXPORT
Proxied Prepending

The IDRP-style DIST_LISTs seem to generate most of the heat.  We never
got a firm feel for why the other two componenents were disliked.

Geoff Huston proposed draft-huston-nopeer-00.txt to attempt to address
some of the route propagation issues that the DIST_LISTs were intended
to address.
