I really hope this is the case, when we were trying to get Penzance PINS approaches approved , both of which terminated over the sea by design, we were told no lower than 500ft, despite the seemingly lower minima permitted in ICAO specification documents. I think it was something to do with them not being aligned with a runway or FATO which was instrument approach suitable, lighting wise.
