Scott Wurcer, former VP of Engineering at Analog Devices used to post in this forum. He knew about these types of things and considered scope waveforms to be valid measurements. In fact he posted this one:
Its just that some people don't know what to make of a measurement unless it gives a number they think they know how to interpret.
To make it easier for some people there is a test manufacturers of opamps do nowadays that gives a number from testing with RF. The number is a DC offset voltage, so someone who didn't understand might think its below audio frequencies so doesn't matter, or is meaningless. However if those people knew more they would know the test gives a DC offset voltage number only because it is a convenient standard way to measure. If the RF signal is modulated like in real life, then the output could be exactly in the audio band.
Regarding ASR, they may be beyond helping. To some extent its like a cult where people have to conform to the doctrine or get out.
However, posting measurements is seems to be okay. PMA posted measurements of RF affecting audio opamps over there. He proved its not meaningless at all. Unfortunately not everything is as easy to measure as that.
