So, do we have a conclusion that toolmakers can reference? Can we document this
somewhere in the specs or elsewhere?

I think maybe actual modelling practice should be taken into account here.
Since these guidelines haven't been available, several important percentages in
published archetypes have been modelled as DV_PROPORTION:
As you say, I think this a case of emerging clarity (or less fog of
confusion!!) as the various use-cases emerge. As the primary author of
both these archetypes, in retrospect I would probably keep inspired_oxygen
as DV_PROPORTION and change pulse_oximetry to DV_QUANTITY but!!! I do not
one thing to note: DV_PROPORTION is a more complex data structure. I
would be tempted to try to determine what use has been made of this
archetype so far - i.e. in creating real data. If no real data has been
created, then it could in theory be changed.

Simple answer - loads of real data - pulse_oximetry and Oxygen levels will
have been recorded hundreds of thousands if not millions of times in
patient data - and Proportion *is* the correct datatype for O2 levels.
