<text> needs to be styleable with html markup.
I think we should try to split your change in two parts:
(1) make string, text and html distinct types
(2) change how these types are quoted
Both changes may break components and demos (at least (1) does, as
you've observed), so we shouldn't step in with the chain saw and then
desperately try to make things working again. So I vote for incremental
