There is some support in now but still a WIP. Linking speed is just one of the factors in choosing a linker, reliability (e.g. known races in gold which is now effectively unmaintained are a problem), or what features it supports. mold doesn't support linker scripts so it is out of question for many use cases, for other use cases it might matter more how large binaries and with what security features in it it creates, etc. I think for building Fedora packages in koji those other factors are much more important than a few seconds saved during the package build.
