Yeah, my point is that those are unusual events, resulting in bigger remodels and associated larger controversies, while even the more routine remodels tend to be controversial.

That is, while the event precipitating it may be somewhat unusual, the situation resulting from the precipitating event, including the large proposed modernizing remodel and the controversy over it, is not at all an abnormal result of such an event.
