Correct, you don't need to sign a futures assignment, you just need to
assign this particular work to the FSF.

It is not sufficient, the FSF needs the copyright for this work, as
do all the other core projects under the FSF umbrella.

I know it's a little more work, but we can help if you're willing

Before we get to that stage though I think we should talk a little

your original email.
