1. Some people wouldn't see an important distinction between PS and DS
since more-or-less everyone has to implement the PS and few features,
once deployed, are totally deprecated. That might influence whether or
not you think its useful to remove it now or at DS. OTOH, if everyone
has to support simple regardless of PS vs. DS, then who cares? There's
no effect on interop.
In addition, DS has become meaningless.
Very few of standard-track documents ever go beyond PS.
