Yes, so I wouldn't advocate removing it entirely (even if I think it
would probably be a good idea).  I'm just saying that I don't want to
make it *easier* to use !important in author stylesheets.

Sure, it would be less convenient in some ways.  It's also better in
some ways - it cleanly distinguishes between the two uses that user
stylesheets are put to.

Importantly, though, it requires zero additions to the CSS language.
Given that user stylesheets are important but niche, finding solutions
that don't involve expanding the language is somewhat valuable.
