One of the more interesting assertions in Accelerated Expertise (that made me dig up the references) is this idea that ‘designer-centric’ product/system design is suboptimal.
You want ‘expertise-centric’ product design instead.

I mean, seems pretty obvious that you’d want to study what experts ACTUALLY do, what cues they pay attention to, and design for that instead.
But since CTA isn’t widespread, most products just go with ‘whatever the product designer comes up with’.

I’m willing to bet there’s a rich literature here. Lots of questions:
- if you design for the expert, say, to augment the expert’s mental models, how does that affect novice users?
- can the product help bring the novice or journeyman up the expertise curve? How?

Yes, and will continue to ask why designers aren’t curious (willing?) to understand CTA?

Oh, I'd like to know your answers! Is it that they don't know about it? Or that it's too difficult to learn?
I know I was certainly put off by CDM's difficulty, and only considered trying it out when I found ACTA.
