No, it's fine with me.

Yeah

  (define-key map [remap text-scale-adjust] 'doc-view-enlarge)
  (define-key map (kbd "C-x C--")           'doc-view-shrink)

should be equivalent.  Well, except that C-x C-0 would also enlarge.  It
wouldn't be bad to have a command to reset to the original size.  That
shouldn't be hard to do.  In the non-ImageMagick case, it's killing the
buffer-local value of doc-view-resolution and reconverting, and in the
ImageMagick case it's just killing the local value of
doc-view-image-width and re-inserting the image with
doc-view-insert-image.
