I don't know if you intended your post (a) as meaning stance no longer has relevance to you as a shooter or (b) stance, as a fundamental component of instruction, in overstated in its importance.
I am erring on the side of caution and assuming (b).
I bolded your Enos quote because it's absolutely true and also completely inapplicable to the instruction and reinforcement of fundamentals. Unless someone is extremely experienced, comfortable with their equipment, and grounded in their fundamentals, Enos' quote has no value.
You can't see what you need to see unless: (a) you know what a technically perfect sight picture looks like for a given shot AND (b) you are sufficiently experienced to know how far from that perfection you can deviate on a given shot AND (c) you can execute substantially all of your shots without falling short on some other fundamental, like trigger control.
Same goes with stance. Until proper static shooting can be executed comfortably and consistently, and until that shooter has sufficient experience shooting from other positions and on the move, that shooter has no idea what components of their body position can be sacrificed without compromising a shot.
People have to learn proper consistent stance and positions, and they have to reinforce those lessons regularly, so, come application time, they know exactly how much they can deviate while getting their hits.
