Who said anything about "disable optimizations"? I suggested a flag to
prevent all subresource loads, not just speculative preloads. Basically
a "treat this as a data document" flag.

Well, what mobify is apparently trying to accomplish is take an existing
(not-mobile-optimized, or in other words typically
ad-and-float-and-table-laden) page and modify it to look reasonable on a
small screen. That includes not loading some of the stylesheets and
various changes to the DOM, as far as I can tell.
