I see some advantages to doing that, but it'd be too much for us to do
to begin with. Let's concentrate for now on the smaller patches and
bug fixes that we have to do.

Indeed not, no.

I don't, but we can certainly start thinking about it.

I know that substantial feature backports like JFR are exciting and
interesting, but that's not the main part of the job. Let's not get
too distracted by JFR from the practical business of making jdk8u work
well: we're in this for the long haul.
