Thanks Christian. I'm reading the BOLTs and reviewing source code now, so perhaps my question / request will be more usefully specific once I've finished that review. Sorry for being vague as to use case for now, let me just point out that the concept of source routing opens up a lot of potential use cases that involve collaborations with intermediaries of various sorts, but for which flexible communication capability would be desirable or required (unless you do that out-of-band, which would be so messy as to largely defeat the point.)
I'm impressed so far by how cleanly and explicitly the BOLTs address extensibility. I find that reassuring, many thanks to whoever applied their technical creativity to this aspect. Was there a BOLT #6?
