1 the preprocessing hook makes sure that no infinite loops occur by restricting the depth of nested directives to 3.
3 this is insufficient in some situations in which sidebars are conditionally assembled from templates.
5 given there are no limits on the number of directives per page and the number of edits a user can do in a particular time frame, i assume that raising that limit slightly won't make the DoS attacks that can be done against ikiwiki too much worse.
7 i'd like to suggest 8 as a new value for recursion depth limit. most people can wrap their minds around a depth 3 nested directive setup, but when you reach a depth of 8, it's likely to be easier to write a dedicated plugin.
