Yeah, I can see what you're saying, but doesn't that also apply to 
repeatable fields? If a particular subfield that is one of a repeated 
set needed to be deleted, it could be identified by a regex or by its 
order in an array (following object syntax probably not correct):

@subfields = $subject->subfields();
foreach $notwanted (@subfields) {
   if ($notwanted =~ /badsubject/) {
       $notwanted->delete_subfield();
   }
}
