Is there a serious practical consequence of this, or was the editing just a convenience ? There must have been some resason we went to the trouble. However based on this being "on its way out" why try to prolong it ? Just drop the subclasses now.

This was just added as a convenience, so it isn't critical functionality.

Having said that, while we could just drop the subclasses now, it would cause a perceived regression in behavior for users running on macOS 10.14 Mojave. So my preference would be to not remove the subclass at this time, but to just not use them when running on 10.15 or later.
