--- Comment #1 from Ondřej Kuzník ondra@mistotebe.net --- This probably applies to all ON/OFF options that don't handle DELETEs themselves.
Note the comment in bconfig.c: /* single-valued attrs, no-ops */
I suppose for booleans it should not be a no-op. For others, it makes no sense to leave the setting without a value, and it's expected that you'll replace the deleted value with a new value.
