We can choose to not package mold of course, but I think it would be a good idea to support mold, because it appears to be much faster than the others. Furthermore, I'd like to eventually switch to mold by default, because it's much faster.  From the README:

mold is so fast that it is only 2x slower than cp on the same machine. Feel free to file a bug if you find mold is not faster than other linkers.

Program (linker output size)	GNU gold	LLVM lld	mold
