Please, let's try to keep this discussion civil.

Being a maintainer doesn't necessarily mean that a particular decision is the 
right one for the project.

From reading both the comments here and in Matrix it seems that forcing mold 
in cmake is causing problems for some people.

For those who want to use mold, setting the linker should be as simple as 
adding -DCMAKE_LINKER_TYPE=MOLD to their scripts.

From my perspective, removing the forced use of mold seems like a reasonable 
approach: it addresses the problems people are experiencing while still 
allowing those who want mold to enable it relatively easily.
