False, entirely. If the custom background is defined in the them, then
it's *always* used. A "no-background" selection is a perfectly valid
selection by the *user* of the theme.

If your method was used, then the user of the theme would have no way
to use the custom background functionality to select "no background".
Removing the class would allow the theme's CSS to come through
instead. That is not the desired outcome.

If the theme defines custom-backgrounds to be used (remember, this is
off by default, a theme must support custom backgrounds), then the
theme should not be defining any "defaults" in the style.css at all.
It's supporting custom backgrounds, it should have the defaults in
that custom background support call.
