This is NOT a slop linker, Mold is a reference in the world of linkers and this port is official.

They just threw out the code base and replaced it with a vibe coded rust port.

"Recent advances in AI-assisted coding have made large-scale rewrites considerably more practical, but they do not eliminate those risks, and we do not take them lightly."

Last time I checked it didn't make any difference or whatsoever when compared to lld so I would not go that far by saying "mold is a reference in the world of linkers" - made a test just few days ago on 10M LoC C++. So, rewriting the codebase in another language just because doesn't seem like an investment worth doing when there's much bigger fish to fry.
