Comment (by nacin):

 As $wp_filter's structure has changed over the years, so has the need for
 this is_null() check. In [6320], some code went into remove_filter() which
 caused empty priority arrays to be unset(). I can no longer reproduce the
 original issue that caused [1394].

 I would not be surprised if we could remove a few other checks as well,
 such as the array cast on the foreach's. I did not investigate that,
 however.
