too me this feels like we are leaking downstream product lifecycle into upstream.
even if redhat is overwhelmingly the majority contibutor of reviews and commits to
ooo im not sure that changing the upstream lifestyle to align more closely with our product life
cycle is the correct thing to do.

at least while tripleo is still in the Openstack namespaces and not the x namespaces.
Skipping upstream release is really quite a radical departure form the project original goals.
i think it would also be counter productive to our downstream efforts to move our testing close to upstream.
if ooo was to lose the ablity to test master for example we would not be able to use ooo in our downstream ci to test
feature that we plan to release osp n+1 that are develop during an upstream cycle that wont be productised.

i do not work on ooo so at the end of the day this wont affect me much but to me skipping releases seam counter intuitive
given the previous efforts to make ooo more usable for development and ci. Moving to independent
to decouple the lifecycle seams more reasonable if the underlying goal is not to skip releases. you can release when ready
rather then scrambling or wating for a deadline. personally i think moving in the other direction so that ooo can release sooner
not later would make the project more appealing as the delay in support of a release is often considered a detractor for tripleo vs
other openstack installers. 

i would hope that this change would not have any effect on the rdo packaging of non ooo packages.
the rdo packages are used by other instalation methods (the puppet moduels for example) including i belive some of the larger chineese providers that
have written there own installers. i think it would be damaging to centos if rdo was to skip upstream version of say nova. what might need to change
is the packaging of ooo itself in rdo.

tl;dr im not against the idea of ooo moving to independent model but i would hope that it will not affect RDO's packaging of non ooo projects and that
ooo can still be used for ci of master and stable branches of for example nova.
