I think we should go for something simple like this instead:

This idea is fine to me. Should a warning message be through here? IMHO
the driver still sends an improper page in, fix it in silence is too
kind or over nice to the buggy driver(s).

I don't think a warning is a good idea.  An API that does the right
thing underneath and doesn't require boiler plate code in most callers
is the right API.

Then I don't have more comment.

Thanks.
