People adding things to the standard kernel (presumably people push their board support in there) would still have to work out which chip select corresponds to which GPIO and write that mapping into their DT with the corresponding loss of legibility there, and of course there's the cost of modifying existing users. It *would* be nice if the mapping to which pin has which function were pushed into the pinctrl driver (and then possibly into the DT for it) but generally this seems like something we should be doing more of not less of.
