This is the solution you want to adopt because you've decided that it's
what you want.  You've said this quite a number of times now.

It would take a lot less effort for you to just describe your hardware
in DT than it would for you to continue repeating yourself, this is a
trivial task.  If the tooling around this is too hard to use then that
seems like a useful thing to work on, having simple ways for people to
describe modules they build for maker type systems (ideally integrated
with schematic capture software) would be great for example.

Both Greg and myself have provided you with feedback which you appear to
be ignoring entirely.  What you are demanding is not idiomatic for DT or
for the device model, this needs to be taken on board rather than just
shouting at us.  Putting a quick hack in that happens to work for your
very specific use case isn't going to give us a consistent, maintainable
and well designed system if it doesn't fit with anything else we're
doing.
