I think this change might be incomplete in a dangerous way. If we no longer look at $e for linking, but we leave $e in authority.control_set_authority_field rows for tag 100 (etc.), then the $e will be removed during future authority propagation. I think this is part of what Yamil was saying in note #1 of comment #4.
I could be wrong, but this looked true in some quick testing. Also, if you test, you will hit bug #712490 as well. I am reopening this bug mostly for expediency, but if someone thinks it deserves a new bug, feel free.
