Your remark on loading order just proves this point: you want resource packages referenced before ‘head’. You should move one step further than the root element, i.e. to the transport layer.

We want resource packages to work for people who don't have the
ability to set custom headers for their pages or who don't even know
what an HTTP header is.  I agree that it's a hack, but I don't
understand how putting the packages information in the <html> element
makes it inappropriate to load from a resource package resources
referenced in link, script, and style elements.

Is the issue just that the HTML file's |packages| attribute affects
what we load when we see @import url() in a separate CSS file?  This
seems like a feature, not a bug, to me.

SPDY will do this the Right Way, if we're patient.
