I'm ok with leaving my reviewed by on _this_ patch because it's so simple but...

In general, when sending a follow up version of a patch, it's _not_ ok
to add a reviewed by tag when a reviewer has not explicitly responded
with "Reviewed-by: ...".  That provides a false sense that a patch has
been thoroughly reviewed.  Responding to a patch does not constitute a
"Reviewed-by:" tag.

And I might be fine with _this_ patch, but that says nothing about
Nathan, whom you've also falsely attributed a reviewed by tag here.

For such a trivial patch, it's not a big deal, but in the future
please do not do that again.  It's ok to send v2, v3, etc, but wait
for reviewers to explicitly state such reviewed by tag. The maintainer
will collect those responses (and can be done so in an automated
fashion via a tool like b4 (https://pypi.org/project/b4/)) when
applying patches.
