I think the reason not all five were added is that only one of them was requested at the time. I believe that was the right decision, because it's generally only when we have a real use-case that the expertise is at hand i.e. the proposer to explain what is required. My understand was that, unlike for sea water temperature, sea water pH would not be meaningful without the scale specified. That is, it's not a matter of technique, but a matter of definition. A better analogy would be that sea_water_temperature and sea_water_salinity are distinct quantities that can't both be described by a generic standard name. I can imagine that if a model had pH, it might possibly need a generic sort, because it might not represent the chemistry properly. However, that hasn't been proposed.
