And we're actively working on filling in those details.  They haven't yet made it as far as an I-D, partly because we'd like to do at least some preliminary testing first.

The present version of BBR, which I've actually seen, ignores ECN completely.  I'm told that the new version which I haven't yet seen, does *something* with ECN, but I'm unclear on what.  I think it'll be up to the BBR developers to decide how to incorporate SCE information, using conventional TCPs as a guide as to what is reasonable - or to ignore it, which is also a valid design choice.
