Right. It may very well be that a single flag specifier (as opposed to
an array) will be enough for this case. If you need to request some
GPIOs as input and some other as output then they are clearly
different functions and requesting them together would be an abuse of
the API.

Not so sure about that - what about requesting GPIOs for a bidirectional
bus?  Thinking about SPI bitbanging here.
