I'm not that convinced the OF IDs should be the default. They are of
course familiar, and some people might have set up special handling for
their devices which makes changing a bit awkward, but we also have seen
issues on all sorts of devices where various OSes and host-based
software makes assumptions based on those IDs which then turn out to
cause problems.
