I think you are damn close and at the same time why should a "stock" anything race be that way ? Because many tracks and promoters let it happen without worrying what it will do to them in the long run. Look at FFW and NMRA as perfect examples of shit getting out of hand on almost every level and people walking away.

Build your car for what you want it to do and if it fits somewhere then so be it. If you want to go class racing just know in advance that most heads up non index racing is way out of hand for the regular person.
