I think I’d call 3e and 4e design pessimistic. 3e tried to codify as much as possible to avoid arguments. 4e actually shows some optimism leaving some things uncodified than 3e codified. But among the things they did codify, they tended to drop anything that anyone might have ever found to be a “problem”.
Yet for most of us, I suspect, these things they’ve tried to fix aren’t really problems.
(Which is not to say that there aren’t good things in the design of both, though.)
