And I RESPECTFULLY will no longer be adding any more songs that fall into this category.
Watch out DB. They will soon be labeling your voluntary restraint "questionable" and "not taking responsibility".

You understand the SHS guidelines and rules very well. And IMHO it is actually questionable for a CC, who would be expected to agree to the site's policies, to express that "what editors decide isn't relevant" to him.
You've just expressed your reaction (i.e. just refraining from the effected activity). I suspect others are silently thinking the same, or at least letting others come and tag entries behind them.
I can respect that these differences (i.e. vocalese, et. al.) are very important to some, but one can't make others think the same. I make a distinction between A Cappella and College A Cappella, but I make no demands on SHS to do the same.
One of my now infamous analogies: I neither live in nor drive through New Jersey; therefore, I don't care what the traffic laws are there. They are irrelevant to me. Similarly, I don't add vids to SHS performances, so the applicable guidelines are irrelevant to me. Again similarly, it appears that DB will no longer add performances that may need one of these tags, which makes all of this irrelevant to him. Problem solved.
Everything comes at a cost. When considering adding these types of complications, the benefits gained need to be compared to the expected costs. I see very little gained, but do see costs that include tag errors, skipped covers, and editor frustration.
