exactly - we keep trying to figure out the right interfaces, but we jump to assume that we know what they are.

If we had the right interface, we would set up the black box, and then put holes/knobs on the box to allow anyone to change the things they should actually need to change.

if we have the wrong interface, then the knobs aren't interesting, and instead we keep end up opening the box, or reaching into the holes at weird angles to do things that nobody knew we'd want to, but that are obviously the right things to do to maximize performance

someday we'll have the right interface, but for now, better to skip the box and do the extra cycles. You're an engineer, you can write a for loop and a switch statement. don't outsource your prompts and give up control flow to save a few hundred lines that will eventually become pretty customized anyway
