I never found that proxy to exist. DMs are individuals, and their style is individualistic as well. It takes into account their likings, and almost always, the players' likings as well. They all "played" D&D.I lived through the clash between ToH-style play and DL-style play. And it's various offshoots, like "rolllplaying" vs "roleplaying". The clash was real.
If I walk into a club and want to know what sort of D&D game is being played, part of what I want to know is Will the GM fudge rolls and/or fiction for the sake of the story? A good proxy 30 years ago was whether their copy of the rulebooks was AD&D or AD&D 2nd ed. I don't know now quite what the comparable proxy would be; but the conversation is certainly one that I would want to have!
And if the question is asked, and they say: "Sometimes I feel like I have to, especially if it looks like a TPK is going to happen." What then?
All that said, none of this has to do with the premise that these terms are useless when discussing how to improve as a DM. And they are too nebulous to support a philosophy that hinges on definitions.
