When you cherry-pick, rebase, or amend, Committer will be automatically
reset; no "games".  The problem with that is there are only two pieces
of information (Author and Committer), so if Pavan (for example)
cherry-picks from your branch, the semantic information that you were a
middle-man would be lost [1].  If that semantic information is about
review rather than IP, I would use Reviewed-by instead of Signed-off-by,
but whatever the convention is/becomes, documentation and consistency is

[1] If he merges from your branch instead of cherry-picking, then your
commit does not get rewritten and his name would be on the merge commit.
