      In my experience, it's the architects who no longer code who do this.

      Isn't that the point? People can argue about models until the cows come
      home. Trying an experiment gives them information that guides the
      discussion. It give bounds when it shows that an approach isn't feasible.

      Yes, and that skill and knowledge comes from practice, not from
      continuing to do the same thing (design without code).

      As you probably know, many of those "whole architectures designed first"
      turn out to be really terrible when you try to implement them. Other
      places, they're not understood or ignored by the developers anyway.
