It's not so much that I missed to pick this up. It's just that it didn't
make it in time. This was posted just a couple of days before v5.4-rc6
and I had already finalized the branches at that point. Given that this
doesn't fix any actual issues it didn't seem worth to force it in at
that point.

That said, I don't have any objections if Stephen wants to pick this up
on top of the pull requests.
