In which cases doesn't it?  If A is the author of B then B was made by
A, surely?

Indeed, but nobody is suggesting that would be appropriate.

Yes, if using rev.  Without rev it could be written as rel=made, because
made is the opposite of author.

Data of what people have actually done, with the existence of current
browsers and standards, informs many decisions.

What semantics do you think authors who wrote rev=stylesheet were
meaning to convey?  Presumably not that the webpage containing it is the
style-sheet for the CSS file that it linked to -- so it's definitely a
mistake by the author.

If what the author meant to write was rel=stylesheet then HTML 5 is
surely an improvement, by dropping the confusing rev=stylesheet?

Or do you think something else is commonly meant by rev=stylesheet?
