[Rdo-list] packaging lifecycles

Is there any documentation which describes the packaging lifecycles for RDO packages? I'm currently using the Juno el-7 packages, and was curious since kilo is coming out now if updates will stop being built there. The 2014.2.3 update has been out for a bit, but I wasn't able to find where if anywhere this might be in the pipeline for update. What is the lifecycle for these kinds of updates? Do you just follow upstream for releases and EOL or stop once a new release is available? Is it possible to get involved with helping on older releases which aren't EOL but don't have updates if they're not normally going to be done?
