In addition, if you are enhancing cat-file to spew chunked

	git-cat-file --batch <list-of-sha1 |
        git-hash-object --batch

should be an intuitive no-op, shouldn't it?

I think that's an obviously good thing to do.  However, given your
suggested output format (which I also like):

   * git-cat-file --batch <list-of-sha1

     outputs a record of this form

          <sha1> SP <type> SP <size> LF <contents> LF

     for each of the input lines.

What should the input behavior be?  Obviously the sha1 will probably
not be known on the input side.  Should that simply be optional (i.e.
it will accept either "<sha1> SP <type> SP <size>" or "<type> SP <size>"
or should it only accept the latter, and a dummy sha1 will need to be
filled in if the sha1 is not known (presumably "000...000")?
