There are plenty of examples of things that “just work” which are poorly implemented.

For example, my life. 😜

There’s a little ditty I like to sing to the tune of “if you’re happy and you know it” that starts “if it’s stupid and it works, it isn’t dumb …”

Not always. I can take the riving knife off my table saw. It works just fine without it, but it’s going to lead to kickback and a very bad day. I’d call removing it pretty stupid.

Nah, I know it’s stupid, and it took way longer than the “normal” way, but it just works.
