Fair enough.

But what of the GPIO_CDEV_V1 option to disable uAPI V1 added in patch 04,
and that depends on GPIO_CDEV?
That is equivalent to GPIO_SYSFS, which is not dependent on EXPERT,
so I'll need to restructure the dependencies so it doesn't
inherit the EXPERT dependency.
Unless you also want it to be dependent on EXPERT.

Hmmm, and maybe patch 04 should be later in the series - after V2 is
fully implemented and V1 is deprecated - around patch 11.
