There are definitely some advantages to switching to lld. espie@ made a bunch of fixes in ports-land for this. Seems like it would be easy enough to test whether an amd64 kernel linked in this way is bootable. The method in the ticket you linked should be good enough for a test. Note that OpenBSD/arm64 is all clang/lld, binutils is not built there.
