Comment (by azaozz):

 Just curious, why callbacks (as function params) and not filters? The
 (basic) difference between callbacks as params and filters is that with
 filters many plugins can apply callbacks at the same time, i.e. work in
 sync. With separate callbacks all plugins will have to rerun the same
 functions again and again.

 Looking ast gthe code here, these callbacks seem like an anti-pattern in
 WP?
