I almost never want paste to preserve any formatting, because I've almost never seen it work perfectly. If I need to reformat it anyway, I'd rather not have to clean up its messes first.

BTW in most programs that handle rich text, SHIFT-CTRL-V does a plain-text paste without the source formatting.

this. the sheer volume of times i have to paste text into a notepad or a URL bar or just any space that will lose the formatting, just to re-copy/paste it into some (usually MS) product that wants to preserve it is way higher than it should be.
