Wearing my Operator hat I don't really care if "LTS" comes from
upstream or downstream. I think the upstream expectation has
developed becuase there has been some upstream efforts and as far as I
can see no recent downstream efforts in support of stable releases,
though obviously I mostly pay attention to "my" distro so may be
missing things in this space.
Having watched this for some time I agree with everything Thierry has
The increasing demand for "LTS" like releases is definitely a tribute
to the overall maturity of core services. I used to be desperate for
the next release and back porting patches into custom packages just to
keep things working.
Now if I belived Ubuntu (which my world OpenStack and otherwise
happens to be built on) would provide a direct upgrade path from their
16.04 released OpenStack to what ever lands in their next LTS I'd
probably sit rather happily on that. Which is a hugely positive shift.

:things like LTS or longer periods of support for stable branches, to

:2/ The OpenStack community thinks this is better handled downstream, and
:we should just get rid of them completely. This is a valid approach, and

Yes it seems that way to me as well.
just killing the stable branch model without some plan either
internally or externally to provide a better stability story seems
like it would send the wrong signal. So I'd much prefer the distro
people to either back option 1) with significant resources so it can
really work or make public commitments to handle option 2) in a
