no, a preload scanner will never (okay, never say never) interpret CSS. This is against the rule of it to improve performance before interpreting layout.
This whole thing is about scanning *something* in early phase, so if some rules prevent from using style sheets for something that is really a stylesheet matter (unless we regard it as a client/server negotiation issue), change the rules.
If some style sheets require early processing, define a new style sheet language (it could very much resemble CSS, too). Or introduce an attribute into <style> that tells the browser to process its content immediately. Then you would have the responsive img settings in one <style> element, all the normal CSS in other <style> elements or in external style sheets. (These approaches have different implications on non-supporting browsers, of course.)
