    Isn't there something to be said for: i) assuming that contributors
    will want to continue contributing; and ii) trying to minimize the
    number of pieces of paper people have to sign?

If someone thinks he may want to contribute more
then he might prefer to sign the future assignment.
The form for disclaimers mentions this option.

     I've always offered
    assign-past-and-future for the whole of Emacs as a default option to
    contributors, no matter how much they contribute initially. Should I
    stop doing this? Is there some reason to actually _prefer_ a
    disclaimer for smaller changes?

The disclaimer is not better for us, but it is smaller and simpler so
some contributors may prefer it.  That seems like a reason to suggest
both options, in the case of a medium contribution from someone who
may not want to contribute more.  request-disclaim.changes does that.
