    But this would mean that merely loading doc-view.el changes the behavior of
    dired-view-file.  Since loading a package should not change the behavior of
    Emacs (because the load may take place for all kinds of reasons), I think
    it's not a good solution,

You are right, but this is easily fixed.  The right way to control
whether to use doc-view is with a variable (if we don't enable it
unconditionally).

The real question is whether to use doc-view or the Gnus mechanism.
