   These will be caught and logged as having errors in the request logger, which maybe seems sufficient for a first pass, but am willing to add additional information if we think it would be useful. I suppose periodic metrics on the amount of queries that get rejected could be potentially interesting in helping operators know when to either scale up or tell the users of certain lanes to chill out a bit maybe? I could look into that as a follow-up PR if we think that or something else would be useful.
