That fact is widely recognised and accepted, Chaps1954. I for one am entirely aware of overnight space limitations. But a considered case-by-case approach to diversion requests allows for all this. It is not an excuse for an inflexible 'NO DIVS' regime to be imposed for days on end without respite. The NOTAM applies at all hours of the day when it is in force ... those stands are occupied part of the time, not all the time. And what of contingency for accepting executive jet diversions? They don't require a widebody stand on T2. The call is for a considered case-by-case approach which allows essential wiggle-room. As routinely happens at every other major UK airport.
There really does appear to be a well-entrenched "can't do" culture in this particular area of the MAN operation. That is a cause for great concern.
