I will conject one possible reason, at the risk of violating the absence of discussion, why this has been declined.

My example:
I recently asked a question which was closed and promptly deleted. It received few views and no votes in the 5 hours for which it was open. (FYI, it has 15 views at time of writing, and 4 of those are mine.) Although the question would've been deleted by the bot in its closed condition anyway, that doesn't explain why it was closed initially.

Perhaps it is because Stack Exchange doesn't want users with less than a certain level of involvement to see the question?
I can only suppose that it violated some taboo, unknown to me, and that the mod who deleted it would rather that it disappear quietly.
Was there some concern that I, or others like me, would pursue a vendetta if the rejection of my question were made more visible by allowing it to remain visible and votable?

Perhaps. I can only say, from where I'm standing, that Stack Exchange admins probably want the ability to hide certain questions from the unindoctrinated viewers or users, and would rather that such a thing be itself hidden. The best way to hide it would be to cloak it in the broader facility that is deletion.
If this factual, then of course the people who want such functionality don't want it to be popular knowledge; such furtiveness is at the very least internally consistent.

Of course, like all puted conspiracies, it would be difficult for me to demonstrate that such a thing is factual. Human psychology allows for the likelyhood; from where I stand, that's all I know.
