The key element here should be unpredictable. For example, sometimes sorting
controls (especially in js-free environments) are represented as form elements.
I think most users would expect a simple sorter (such as an arrow button next
to a table header) to autosubmit. Likewise with paging controls.
In addition, consider a corporate environment where web pages may be modeled
after certain desktop applications. If that application autosubmits, then the
user will likely expect the web page to do likewise.
If I may make a bad pun, sometimes what is unpredictable to the user is not
always predictable.
