I think you missed my point.  I'm not saying it isn't a reasonable change, but that they are not always subcards.  If a *structure rule has an absolute cardname, then that card may be edited and show up in subcards even though it is just another potentially unrelated card (or related only by inclusion to be precise).  I think the name is fine because it is the typical use case, and the situation I'm talking about is very much a special case.
