If it's reviewing the implementation, that's a second review. Which is
fine if that's what we want do do.

Again, I say: that's what the review process is for.

Neither do I, but it seems pretty clear to me that the approval
process in this case is not actually happening. There's a review, the
approval box is ticked, and in it goes.
Having said that: is there a problem to solve? Are we allowing broken
or inappropriate patches through? I don't think so. If not, we're
merely worrying about correctly following a process rather than
ensuring the quality of OpenJDK.
