The problem I see with adding blob support to ResourceHandle is that it makes it too difficult to maintain. It used to be a platform abstraction, and it was hard enough to make sure it worked well across platforms. Adding a significant amount of cross-platform logic on top of that isn't going to make it easier - especially when it's done via subclassing.

An example that prompted me to look into this was <http://trac.webkit.org/changeset/67503>. Here, a static function that reported platform capabilities had to become virtual, so that it could take blob loading logic into account. There is nothing in common between "are we running on a version of Mac OS X that supports this" and "are we loading a blob", and remembering this twist won't be easy.
