But that has the exact same problem as the other approaches proposed,
which is that in order to convert a driver, all the platforms in all
archs that use it need to be converted to use the new mechanisms,
properties etc...

This is going to be really hard since we don't have access to all of
that HW and will introduce huge lag as I can expect the various embedded
platforms maintainers being in no hurry to help initially.
