That's a neat proposal! BTW I totally agree with your point about forcing
qualified ids in general, my experience also when looking at large
codebases. One of the first reasons I began to prefer Oberon to Pascal.
In terms of your code screenshots, I like both of them (although it did
make me wonder if these peripherals are in a Cortex bit-banding region -
it would be neater if they were! - but that's not your point).
However, my general experience has been that any labour-saving device I
used when writing code has seemed a terrible idea when trying to read it
again some time (possibly much) later. I actually want it to be verbose
(but not overly so, of course) when I'm reading it.
So I would say I like your idea, against my better judgement ;-)
