I think the best approach here is to go forward with the quirks mode 
spec proposed at http://simon.html5.org/specs/quirks-mode and have 
browsers align on it.  The CSS parser spec would need to support 
whatever quirks end up standardized.

In particular, the "no unit" case does need to be handled in some 
properties for web compat (section 4.2 at the link above), but the 
"space between number and unit" does not, based on implementation 
experience.  Specifically, some UAs do not implement the latter quirk 
and it hasn't been a problem, hence that quirk is not needed in practice.

Seem reasonable?
