Yep, the feedback book thingy is the 5.12-specific portion of an up-to-date bridge kicking in

Everything looks good

Thanks for the prompt feedback, this little adventure has convinced me that the bridge really ought to take care of ;log because it did save our bacon in the past (@hius07 will be happy ;p).
Harmless sidenote: installing the current snapshots will technically have downgraded your bridge, but that's harmless for now (and a necessary step because otherwise it'd have restored potentially buggy/incomplete backups).
I'll be throwing a big fat warning when I next update the snapshots that everyone should update their bridge ASAP
