Since Signed-off-by is going to be required, automatic check would be
doable. After all at some point in the past you mentioned either
Signed-off-by from someone with commit access or Reviewed-by could be
required. However anyone pushing a patch is either the contributor or is
apparently confident of the patch to the extent they could provide
Reviewed-by so the condition is implicitly met by the fact the patch was
pushed. In other words, having Reviewed-by in the commit message is nice
for generating statistics for KVM Forum keynotes, once the patch gets
out of our git repository (i.e., is backported to a downstream), or when
someone wants to see who the hell could have acked this. But it's not
something one couldn't live without.

That said, I don't mind if either of these tags are mandatory as both
are somewhat useful.
