That's a fair amount of research you've done in compiling your response. Thank you for this effort.
My main aim here was to add, rather than remove. I'm guessing (and correct me if I'm wrong) that you brought up cite as something to be removed. While I won't be adding it to this proposal, you are, of course, absolutely free to start a "Removals from Approved HTML" thread.
I included dir for reasons of consistency: it's already allowed in one place, so why exclude it from others. I'm fairly certain I've never used it on this site, but I most definitely have used it elsewhere for arabic text. (Hebrew text would be another place where it would be appropriate.) Thanks for the feedback: if enough people don't want dir, I'll remove it from the proposal.
wbr: you learn something everyday. I'll change the proposal to document and get rid of the suggestion for removal.
