How important is the word "implicit" in the title?  Is it your
intention to actively ignore --signoff when we fall into the
rebase--interactive codepath explicitly?

I offhand do not think of a strong reason why it is a bad idea to
run "git rebase -i --signoff", turn a few "pick" to either "reword"
or "edit", and then expect that the editor to edit log messages for
these commits to add your sign-off when you start editing them.
The "pick"s that are left as-is would also turn into doing an
otherwise no-op "commit --amend -s", I guess.

If you are teaching --signoff to the whole of "rebase--interactive",
then "git rebase --help" needs a bit of update.

    --signoff::
            This flag is passed to 'git am' to sign off all the rebased
            commits (see linkgit:git-am[1]). Incompatible with the
            --interactive option.
