With birds as with people: What looks like the cool new trendy place to live slowly becomes that place that lets everyone in, and the trendsetters move along to some new hot spot. This dead trunk was clearly very popular with woodpeckers for a time — I occasionally saw them very nearby but rarely saw them in these nests — and eventually they just packed up and moved out. Of course, they make their own housing, so once a trunk they love has become so dead that the insects they love have moved on, they can move on too.
