Comment (by smerriman):

 Are you going to hard code in a special case for site icons, or will the
 logic be able to be applied to other sizes? For example, a theme I've
 built uses the same type of code to generate a special logo size; that
 also gets lost on regenerate. That's why I was thinking there needed to be
 some sort of flag stored with the image on core's side that the call to
 the function could ignore.
