There was a trust router release in October. At one level, this release is probably functional enough that it would be nice to have included in stretch. At another level, there have been enough upstream bugs files that I don't think it's stable enough to include and support for the lifetime of stretch.
However, I think we're in a good position to put something into experimental (and then stretch-backports) very soon. Also, now that freeradius 3 is in Debian, we should be able to get that infrastructure enabled. I think shortly after the release of buster, we can close this bug and let moonshot-trust-router migrate into testing.
