I agree with Robert. Today, there are many tools that interact with BGP messages. If the AS_PATH disappears, they will all break.
Indeed. If mandatory, well-known attributes are removed, then the BGP protocol version number needs to be bumped.
There's near-0-cost in doing that for those interested in implementing the new functionality, and it avoids a world of hurt for all the various tools (sometimes in-house/home-grown) out there that believe they know what they're getting when the version says 4.
