Well, no, sorry :)

I don't think it is a good idea to allow drivers to opt-out of the
strict-setting. This is a platform or user decision, and the driver
should accept whatever it gets.

So the real question is still why strict is the default setting and how
to change that. Or document for the users that want performance how to
change the setting, so that they can decide.
