i am -1 one on that, it is a checklist, not really an information for the user of a bundle. we do have this checklist in https://github.com/symfony-cmf/symfony-cmf/wiki/Roadmap where it is useful to track how we proceed.

we can say here that a bundle may not be tagged stable if it does not fullfill the criteria of this list. and maybe have the README say that this is a bundle of the cmf and follows the standards and link that information to this doc page.
