I didn't mention this in the cover letter but I update the review tags at each version. The problem is that if someone has reviewed a commit, and then that commit is subsequently changed due to another reviewer, I have to remove the existing tag of the first reviewer because the code has changed.

It seems to me like you did the right thing here, the changes you did between v5 and v6 were substantial enough they invalidated the Reviewed-by tag(s) you had gotten previously.
