Isn't that what I suggested?  I suggested that it be asyc, just as you said
- and that all we do is add the ability to use the :unresolved pseudo class
on the body.  This provides authors as a simple means of control for opting
out of rendering in blocks above the level of the component without
resorting to the need to do it via script or a root level element which
serves no other real purpose. This level of ability seems not just simpler,
but probably more desirable - like a lot of authors I've done a lot of work
with things that pop into existence and cause relayout -- often the thing I
want to block or reserve space for isn't the specific content, but a
container or something.  Seems to me with addition of a body level
:unresolved you could answer pretty much any use case for partial rendering
from "just dont do it" all the way to "screw it, the thing pops into
existence" (the later being the default) very very simply - and at the
right layer (CSS).
