This is a legit complaint. The removal of drop shadows makes designing for iOS harder than before - and Apple does demonstrate poor legibility in some places.
I think we're going to end up moving, funnily enough, to something more like Metro. The design language in iOS7 calls for big photos, and lots of text overlaid - IMO the default don't-think-too-hard-about-it solution is going to be slapping semitransparent colored bars down and putting the text on top.
Which, honestly, isn't all that different from what you used to do. Rare was the app that put text directly on top of uncontrolled (i.e., non-curated) images. Most text already existed on their own surfaces (instead of complex photographs) to begin with.
