Nick,

There could be not so many clients negotiating it with RS as they do not
know that RS supports it :) So why not enable it on RS side and let BGP
capabilities negotiation do the job ?

At least BIRD claims to support it for eBGP in add-paths implementation
report:

CZ.NIC         (iBGP) route reflector / RR client, *(eBGP) route
                server / RS client,* use cases where paths are
                distributed for other purposes than filling FIBs (like
                topology-aware CDNs).



I guess those clients who care to get all eligible paths will take
some actions to enable it on their side sooner then those which do not
care.

Cheers,
R.
