I think the new behavior will be a subset of CSS ruby. Blink will be
compatible with CSS ruby box generation, but web authors won't have a way to
specify ruby-base-container and ruby-text-container to elements.
OK, that seems reasonable. So therefore if the author writes in their
stylesheet:
ruby { display: ruby; }
rt { display: ruby-text; }
rb { display: ruby-base; }
They will get the exact same rendering as in Firefox for all markup
permutations of <ruby>, <rb>, and <rt>, correct?
If that's true, then I agree with setting those values on <ruby>, <rt>, and
<rb> and shipping such an implementation.

I don't think WebKit is against the specification though their ruby
development is not active.
Sorry, I wrote that confusingly. WebKit's position is *regarding* the whole
spec. :) They are obviously in support.

We don't have an implementation of this change yet.
I think it would be good to evaluate the change before deciding whether it's
ready to ship. If you don't have an implementation, you can't evaluate which
bugs need to be fixed before you ship vs which you are willing to fix afterwards.
