No, I’m not. OP is conflating multiple guidelines for different purposes and attempting to use them all simultaneously.

No, he's literally explaining why the guidelines can't be used simultaneously.

They aren't supposed to be used simultaneously, which is literally what my comment was explaining. Different guidelines to solve different problems.

Have one source of truth is a universal guideline.

Prefer structs over classes is a universal, if weak, guideline.

It's funny how people can be all hung up on composability of things like type systems, and then completely blow off the desire for composability of guidelines.
