At some point, years of experience is MORE important than lab studies and test results.
It is wise to be cautious of change, until change has been tested by time. It was not long ago that plenum systems were "proven" to do a large number of things in marine reef applications. The greatest names in the hobby supported the ideas. Until the systems crashed and problems became apparent, some several years after the systems were set up. I seem to remember Strontium supplementation also being necessary as confirmed by scientific studies, until further studies found Strontium to be toxic. It also seems that Nitrite readings in marine systems are still highly utilized, despite the fact that Nitrite is not toxic at a pH over 7.4.
There are a great many things in this hobby that evolve, you are exactly correct. This is the reason that we need to rely on the personal experiences of those who have consistently duplicated success over long periods. These are the people we need to look towards and ask HOW they have duplicated these results. I feel that Byron is himself a good reference, and is somebody that probably deserves a bit more credit as an authority on the subject being discussed.
