"...it doesn't do any real work in parallel." I think this is the biggest selling point.
Although, "with GNU ld you might have to wait several minutes of link time on every dev build." Meh, I might prefer to wait a few minutes and stick with something I know works.
"The creator of mold is also the original creator of LLVM lld" That's cool, why not implement these features in LLVM lld? Why not implement them in GNU ld? Is it a gatekeeping thing? Parallel ld would be very useful.
No, it's not a gatekeeping thing. You're coming at this with negative assumptions, so I don't think I can try to convince you. If you hate Rust and want something conservative, then use lld. It has some parallelism, but it's fairly coarse and still has single-threaded bottlenecks. It would have needed a pretty major re-architecture to modernize it.
As for trying to do that in BFD, patches welcome. Or maybe not welcome, I'm not sure the maintainers are really looking for a major redesign of GNU ld. But either way I'm not volunteering, it's much easier to start fresh than try to carve out and replace the entire guts of this old thing.
"You're coming at this with negative assumptions" not so much negative as skeptical. Everyone is pushing Rust and full rewrites, I'm still not convinced.

Also, why Rust?

Fair enough :D
