Yes I meant the kernel only; I was optimistically thinking they
wouldn't break ABI between minor versions but maybe that is fatally
wrong to assume. I minimally tested running wheezy/sid system including
ZFS on a 9.1 kernel some months ago.

I think I could accept the risk. I only found one or maybe two things
that seemed viable to backport to 9.0, whereas many more people have
driver issues that only an upgrade to 9.1 could fix.

I'm concerned by the rate that some things are changing recently, mostly
in packages that have close Debian/Ubuntu co-ordination (which includes
GCC), and it is usually at the expense of the architectures Ubuntu isn't
selling (which are only Linux i386/amd64/ARM).
There is expected to be a gcc-4.9 appear in the archive soon, and I
wonder if gcc-4.8 is really going to stay, remembering what happened
late in the wheezy release cycle.
This is very much a personal opinion but maybe clang-3.2 could be easier
to keep up with for the jessie cycle. This puts me slightly in favour
of trying clang-3.2 but unfortunately it is a preference not based on
technical merit.
