I agree: makers and tinkerers definitely need this flag and it will further
emplasize the transition to the character device and to the v2 character
device interface (which, by the way, is looking awesome, especially when
taken into the picture the libgpiod changes and the new language
bindings for libgpiod).

So we need to add this to become ever more appealing for one-offs
such as industrial control.
