[resource-hints] Resource de-prioritization?

Hello all,

Please excuse me if this has been covered already. I could only find a
single thread reference on the mailing list (
http://lists.w3.org/Archives/Public/public-web-perf/2013Apr/0060.html) and
no response from the draft authors, so I’m bringing it up again. If there
is another thread that discusses this, I would appreciate a link.

In April of last year, Jake brought up the "defer" attribute for images
(and other resources). In reading the Resource Hints draft, the concept of
lazy loading or allowing the browser to determine the loading process, but
to be aware of a low-priority resource seems to have been lost. It was part
of the now-abandoned Resource Priorities draft (defer, lazyload). The
Resource Hints draft seems to focus entirely on prioritizing assets and
domains (which is understandable), but does not seem to offer an option for
de-prioritizing assets. Are we to assume that deprioritization would be the
default behavior if prioritization instructions are provided? In not, where
are we at with respect to a declarative de-prioritization instruction?

Cheers,

Aaron
