I agree there's a different level of resolution being demanded at this
point. This is due to the huge installed base, namely the web. In CSS
we had the privilege of starting from scratch (at least for the syntax).

These days, I see a lot of sites using CSS right. Still, we will
always be stuck with tag soup. At some point it turns into historical

I disagree with you here. I think draconian is user-unfriendly by
