Hmm, you're missing something: in both your examples the whole rule

The examples referred to different cases. Your example uses url(#) in
place of a background image in the background shorthand and becomes
overridden by a background-image declaration. The rule was meant to
stand as is, and as I wrote, in that case the best approach is to omit
url(#) - so the shorthand will set background image to none.
Another case is the use of url(#) as a placeholder to be later replaced
by the real URL. In that case, its being a formally valid URL is a problem.
So, depending on case, url(#) is either useless or worse.
And of course, the whole issue should be avoided by arranging
things so that such "placeholders" are not needed.
Think of something like this: skins for a forum or a web app. The
main stylesheet has all the structure, and most parameters for
background(-images). A second stylesheet (loaded based on user
preferences, stored in a DB or via cookies) then loads the colours
and background images. The background-images are stored in a sprite
that only varies in colours (to match or contrast fore- and
background-colors) per skin/theme.
Yes, and? There is no need for url(#) here. Is that what you mean? It
would be more interesting to see a case where someone thinks that url(#)
is needed for some reason.
