This would be a warning with _RELAXED/_CONSUME, but there may be very 
obscure situations where someone really wants that (but then there
would be no way to get rid of the warning). So if you do that you would
need another flag to disable the warning.

The "default to ACQUIRE/RELEASE but allow override with no warning" model seems
more user friendly to me.

You assume they really want one :-)
