I think I’d prefer you fixed the behaviour 
Regarding the documentation, I see you’ve updated DELETE but not DROP SERIES. I think both need to mention this limitation. Can I suggest the following wording for DROP SERIES:
DROP SERIEScannot be used to delete a measurement series which contains data points with timestamps in the future. UseDELETEfor deleting such measurements.
And for DELETE I think you’ve got your wires crossed - there is no command “DELETE SERIES”. So maybe that note should read,
If you need to delete points with timestamps in the future, you must specify a time period in the FROM clause because DELETE runs for time < now() by default. For example,
DELETE FROM "h20_feet" WHERE "mytag"='tank 1' AND time < '2100-12-31'
And don’t forget to publish this to the web site at https://docs.influxdata.com/influxdb/v1/query_language/manage-database/ when you’re done
