Because I know my responses don't actually matter and that almost none of us are ever convinced of other people's arguments?Your percentages aren't accurate nor can they be, and only exist to make the opposition look stupid.
As for the rest of your post, there's a lot of room between Ask DM and having more specificity. You reducing it to a binary and saying that people can't agree on things so there shouldn't be any actual new rules is logically nonsensical, and requires you to jump between extremes to make sense. C'mon man. You're smart, I read your posts. Why rely on such inherently bad-faith arguments?

Yep, I hyperbolize sometimes. And if I get called out on it (like you just did, and with very good reason)... I can admit it. Yeah, my percentages had no basis in fact, that is true.
But it also doesn't change the crux of my argument that wanting specificity is only useful to a person when that specificity is the way they want the rule to go. And if they don't like the specificity, then what did that specificity gain them? Ask any of us how we want Stealth to work (both in and out of combat) and almost every person will have some different way they think it has to happen. There will be no consensus. Just like there's no consensus on how a Psion or Warlord should be made for 5E.
At least with more generalized rules that are meant to be tweaked and made more specific by a particular DM at their table... or changing rules they don't think work very well via "Rulings, not rules"... any DM has a much better chance of actually seeing the play they like.
No one should want ironclad and immoveable rules in D&D. Cause you ain't gonna like everything that you get.
