As Boris has explained, it's not performance issues, but rather author expectations. The average author expects a CSSOM to exist for all the stylesheets in the page, and when the set of matched MQs changes, for the styles to change at the same time, not a network-roundtrip later. If any browser *did* defer them indefinitely by default, they'd get compat bugs. ~TJ
