This is what I was trying to express in linebender/glazier#149 (comment)

I don't see any feasible solution other than maybe reporting these through a webhook on Zulip? That is kinda terrible UX though
Because these are nightly docs, we don't want it to break/block randomly for contributors

I understand and share your frustration! I don't have an answer at the moment or I would have included it in this PR. :(

[DJMcNab]

Yeah, no worries. I'm happy to get this landed though. I'll let you press the button

I'll add it to the queue just to make sure it won't miss the release train.

@xStrom Thanks. I had a bunch of meetings and stuff and got lost.
