Professional & advanced web authors are going to want professional &
advanced functionality, and it is these people that are most likely going
to decide the fate of CSS et al.
Web authors, no matter how profesional, aren't going to having anything to
play with or at least anything consistent to play with if implementors
don't provide an even level of support due to varying complexity of features.
Tell ya what, why don't you poll the UA vendors to see who is going to
implement *everything* in CSS1 as currently specified such that they will
claim to have full CSS1 support. Also find out when they are going to
support it *completely*. Let us know the results.
CSS1 should have nothing more in it than a majority of UA vendors say
that they will support in their first release of CSS support.
To quote Larry Masinter, whom I'm certain was quoting someone else,
"when in doubt, leave it out."
