From IRC, this comes from funsize picking up ACCEPTED_MAR_CHANNEL_IDS at https://dxr.mozilla.org/mozilla-central/source/release/docker/funsize-update-generator/scripts/funsize.py#212 and that's dual-valued on beta for rc-on-beta http://hg.mozilla.org/releases/mozilla-beta/file/default/browser/confvars.sh#l51
