Mostly because it might not interact so well with deferred probe, lots of drivers only request/figure out the GPIOs in setup at the minute but for deferred probe we ought to be doing it as part of the main driver probe(). We should also be switching away to the GPIO descriptor API is part of it, but also I want to do a pass and add standard DT bindings for this.
