If tripleo (or others) are willing to help care for those images and fix them when they break, we should be able to support them through the entirety of their designated lifetime. I do not expect we would keep images around for releases that have reached their end of life. It just isn't practical to try and keep up with security issues, and we should move on.

Yes we would assist in addressing breakages as necessary and also
agree about not keeping them past EOL.  We'll probably end up
targeting having some sort of basic gate job during stein so we'll be
very aware of breakages.

There is the possibility that ansible's python3 support is working well enough that we could switch to it, but that requires testing and updates to software and images and config.

Hmm ok, we'll have to make sure that doesn't conflict. Good to know.
