What I maybe misread in your concern: The dev interface is actually an "alternative to sysfs for block GPIO", not considered as a replacement for the current sysfs interface for _single_ GPIOs.
The fate of the latter one can be discussed separately.
Also, the sysfs interface for block GPIO can be left out of my patch series, if necessary.
