It's also slightly harder to say (and to code) "A data: URL that is more than X bytes when stripped of its prefix up to and including the 'base64,', then converted from Base64 to binary" than it is to say "Any URL that is more than X bytes." But it's obviously not very much harder (except for someone coding this up in XSLT, but I don't know how many people other than myself are that masochistic).

    I can see why people would want to use the encoded form, because
    that's what is likely processed in aggregates and so as Ian rightly
    points out it's easier to just consider the whole data: url.
    
    The reason we use the unencoded form is it is easier to explain to
    the technical staff at various providers. It refers to an actual
    file size they can see on disk, and is something they can readily
    ask their graphic designers to produce. "I need a logo that is x by
    y, but it must be smaller than 40KB."
    
    IMHO keeping it simpler at that end is more important than the
    once-off cost of dealing with the code complexity :-)
