There was a time when vendors were actually ran by engineers :-).

I recall asking for the feature from Cisco around 2011/2012, for the 
ME3600X/3800X, and that's how it arrived. The team developing that breed 
of box were excited about the prospect of its success, since I began 
working with them to develop it in 2009. So they rolled out as many 
features as I could help them make sense of, and BGP-SD was one of them.

The good news is it made it into IOS XE, and became available for a ton 
of other platforms, the ASR920 included.

Nowadays, one wonders who's actually running the show at vendor-land...
