I doubt we've documented the workaround I described, no.

We do not expect change streams to continue to work after removing a
shard, so there's no value in testing it.

schwerin I'm marking this ticket as 'documentation changes needed', recommending we document that we do not expect change streams to be able to survive a shard removal. You mentioned during triage that there was a known workaround involving zoned sharding that would allow an admin to remove a shard without disruption? Do we have any documentation of such a workaround?
