So I looked back over some of the relevant passages in the PHB and DMG and the things some people have been saying and I think I assumed people were saying a lot more than they were saying. The way the game lays it this stuff it tells you what happens at the table - not how it happens. There is nothing about how a player should decide what their character does or how the DM should decide what happens. I was assuming a strong link between a player's stated (or implicit) goal and what DM decides happens.
From my perspective this makes it broadly useless for actually talking about GM technique. Technique is a matter of how we do things. If we are not actually talking about our decision making process as GMs, what our actual priorities are in any given moment of play, then what are we actually talking about?
Given room for implicit goals it also basically describes every traditional game ever. This is basically The Golden Rule wrote a little differently.
I get that players calling for a given check is a thing that happens in play, including a lot of Fifth Edition play. It happens regularly in the game I am a player in. Still I have not seen a single text implying that is the way things are supposed to go down. Nearly every traditional game I have ever read says something to the effect of players should describe what they are doing and GMs should call for checks as appropriate.
