Purpose of a procedure
Perhaps if we split up the ideas, then we can develop procedures and apply them at the right time.
There are procedures to protect the ILS signal. These are required for when the aircraft requires them, and that is RVR less than 550m. Keep on packing them in until then. After the second go-around, maybe it is time to slow it down a bit and go to CAT II or III approach separations and use the CAT III holding positions. As for me, I think you should always use the CAT III holds anyway.
There are procedures to protect the lack of vision from the tower. I would suggest that these may be more appropriate for operations in the dark and also in visibilities significantly higher than RVR 550. If you cannot see a grey truck on the concrete at the other end of the aerodrome, you might want to go "procedural" with ground operations. This requires the locking of gates, lowering of barriers and the rest of it.
When there was only one Trident or Caravelle on approach, it could be a combined procedure and nobody minded. With well over 90% of aircraft at some airports equipped to CAT II or III approaches and low visibility take-offs, is it not time to take another look at why the rules were written that way in the first place?
