I fully agree to the API change argument to start with 16.07 and the 2 year cycle (more would be nice, but this means effort and after a while almost nothing is "easily" backportable). Never the less I have to ask - as I'd be personally much more happy if it would be the odd years autumn release that would make the LTS as it would match our LTS releases much much better. Otherwise we (Ubuntu) will always "just miss" the LTS by a few months. First I'd have thought on xx.02 releases, but consuming applications might need time to adapt and while there are the nice API/ABI guarantees experience tells me to better leave some kind of time-buffer. Also this would give all of us a first shot with a shorter (not so long as in L) LTS to see if the process we defined works out before jumping on a full 2 year cadence. So while I see that this is kind of "my problem" I would at least try to personally ask and vote for LTS being: 16.7, 17.11, 19.11, 21.11, ...
