I am not super well versed with the lld code, but it seems to be very similar to the code in the ELF subsystem.

It would be great if we could get this approved and merged and backported to 21.x to have this feature completed by then.

Did you end up merging a release note for this @bd1976bris ?

(@aganea might be able to review the lld code as well).
