Peter,
I do not understand why you are not the first person to say that Adobe
tool like InDesign is not perfectly, entirely compliant with CSS 2.1 to
begin with, to start with and it should be entirely compliant with CSS 2.1
(and possibly ATAG 1.0). Standards are mutually beneficial to compliant
parties.
There is no compatibility/incompatibility problems (headaches, nightmares)
if we all follow and implement W3C web standards.

Which cases?
User agent stylesheet have default margin values for various elements.
eg.
p {margin: 1em 0em;}
h1 {margin: 0.67em 0em;}
etc.
CSS2.1 User Agent Style Sheet Defaults
http://css-class.com/test/css/defaults/UA-style-sheet-defaults.htm
and
Appendix D. Default style sheet for HTML 4 (informative, not normative)
http://www.w3.org/TR/CSS21/sample.html
provide more information on all this.

> If leading model is going to become more flexible,
I am inclined to be against adding anything else until the problems
listed, carefully explained with regards to section 10.8 of CSS 2.1 are
not addressed to begin with. Anything else added into the leading model
(CSS3) needs to be extremely very well justified, substantiated.
