That can certainly be the case, but in other cases e.g.
the change is quite trivial (both the original change and the backport).
My point being that the onus is on the person posting the CFV to make
sure that the contributions of the nominee can be clearly seen. In the
case of jdk-updates and backports it is exceedingly difficult for voters
to be able to know whether a backport was trivial or indeed reflects a
significant contribution from someone else. As you note the process
itself is flawed because the involvement of someone in a backport is not
even be visible in the changeset. :(

Thanks for clarifying that.
