Indeed it is the case and the only reason that rebooking would be allowed to other airports is a material delay (which seems to be more than 2 hours) or mass irrops, in which case someone may press a special button and all airports are enabled.
See posts 5, 8, 9 and 11 above for the earlier discussion on this.
