Typically things like this have binary compatibility reasons. (It wouldn't be because they forgot, actually I happen to know the same person has worked on dyld since the 90s.)

Funny thing to complain about. Sloppiness /is/ Unix design, that's intentional. It's called "worse is better".
On the other hand, nobody uses Plan9 because it's too well-designed to actually work.

That's missing the point. It's about simplicity through well designed abstraction. Unix was a runaway game engine that became Bell Lab's standard for talking to computers because it was vastly simpler than the poorly engineered MULTICS and friends. That's why it won.

I use Plan 9 every day. I'm replying to you from inside abaco. I run a tablet with it, have a whole network of machines (most of them virtual). I'm in the middle of a project to create a light fixture I can talk to in 9p. It's not the first DIY IoT thing I've made to control over a Plan 9 terminal. My grid also runs my email, my file servers, an LLM chatbot (though this is actually served from a Linux machine via Inferno tsk tsk.) The only reason I use anything else is due to my job requiring me to ship a product in C++ and OpenGL. For something that doesn't "actually work", I find that it actually works excellently.
Go programmers use something Plan9-y, but I don't think much of Go's design either; it's a combination of Unix's underdesign with Plan9's inflexible and idiosyncratic taste.
