Sure, why not?  Why would this be limited to File objects?

A File is supposed to refer to an actual file on the local hard drive.
 A Blob is a big bunch of data that you might want to do something
with.  There's nothing special about a File when it comes to what
you're doing with the data.

Just as we moved File.url up to Blob, I think File.readAsDataURL
belongs there too.
