rs-bfd started with that as a likely way to handle carrying the RS state.
However, we reached two conclusions:
- the draft was inactive.
- and even if we used it, it was an awkward fit for the mechanism.

https://www.ietf.org/proceedings/93/slides/slides-93-idr-3.pdf

Similarly, BGP-LS was given a try and decided to be too heavy weight.

So, we're closer to where we started. :-)
