I'm not confusing upside down holes with holes that have no scoring spread.....I'm combing them into a category of holes that are wasted with regard to the purpose of the course: to crown a champion based on skillful play.
The "a little above and a little below" par thing is of small value or interest. Of interest is holes that produce a decent number of each of 3 different scores (birdie, par, and bogey.....and a few eagles and double bogeys sometimes on multi-throw holes). It really does not matter if birdies slightly outnumber bogeys or visa versa.
I'm a little confused by your second paragraph. It seemed like earlier you had an issue with holes that were in that scoring range, this post says you want good scoring spread and don't care if that comes from the x.7 or the x.3 holes. I agree with the points you make here, it just seems like a different opinion than you had a page or two back.
