We are moving away from the global GPIO numberspace used by pretty much only the deprecated (since 5 years+) sysfs. The reasons behind deprecation of sysfs and the GPIO global numberspace is detailed in our TODO: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpio/TODO What we encourage as GPIO maintainers is for consuming projects to use the GPIO character device utilizing the libgpiod library: https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about/ The library comes with a few example tools that are pretty useful for tinkering and experimenting with the character device. I'd be thrilled if libgpiod could be included with OpenWrt given how much use it actually sees in GPIO-based automation despite its roots in routers.
