Thank you. I believe there's a vanishingly small set of projects that rely on behaviour unique to GNU ld, can't be trivially updated to accommodate LLD, and can't just link with GNU ld instead, via -fuse-ld=bfd.

Our experience with Clang in FreeBSD is broadly illustrative - Clang is our /usr/bin/cc and the vast majority of the ~25K third-party ports build and work just fine despite minor differences compared with GCC. A few hundred do not, and have an explicit dependency on GCC. The same thing can easily be done when we bring in LLD as /usr/bin/ld.
