In #93268 we introduced a stop-gap measure to support showing region information in the SQL Activity pages for the 23.1 serverless preview. That mechanism was expedient, but barely correct and problematic.

We have since, in #95449, provided a more robust solution, and, once we switch to using it in #98056, we should revert the work of #93268 to clean up after ourselves. (Indeed, we don't want to release this partial /_status/nodes implementation in 23.1, so I think this should be considered a GA blocker.)
