Consider I've chosen 'black' as my default background color. Your
stylesheet now reads like
body { color: black }
Now back- and foreground colors are equal and I cannot read anything of
the site. To avoid such conflicts, the validator warns.

Zero (0) has no unit, it doesn't matter if it's 0px, 0cm, 0mm, etc.
Other units aren't stripped. The "pretty printer" has a lot of bugs and
shortcomings, I don't think it's a good idea to use it's output at all.
