I read this differently.

I don't see any reason why only a relevant part of a patch can't be
covered by a Reviewed-by.  It doesn't explicitly say that you can't do
that.  If the statement meant that, it would have used more inclusive
language like "whole patch" or "all of the patch", but it refrains from
doing so.

My interpretation is that the explicitness of the Acked-by statement is
to provide extra protection to Maintainers that only review and provide
Acks for chunks that they are responsible for.

Whatever the case, this is a pretty nitpicky point.
