It's not the case that these boards (even when used with flying wires)
universally want or use spidev, people will want to use existing drivers
for devices that have them, and equally there are a bunch of non-maker
applications for spidev.  It's not like there is a special kind of
silicon that only makers use here.

There's a bunch of work going on to make overlays easier to use with
connectors which will hopefully help a lot here.  The other big bit that
seems to be missing is automating the process of going from schematic
capture for the modules to DTs so that people can design something and
get the bits needed for the software as trivially as possible.
