What real purpose does $.noop() serve in jQuery 1.4?

Question

Pouring over the release notes regarding jQuery 1.4, I came acrosss $.noop() which is:

Description: An empty function. (added in 1.4)

Answer 1

Probably if some bad API requires a function as a parameter, and you don't want to do anything in it, this would be a framework-supported way of making that obvious.
