The unpleasantness of reading continual criticism, from those who will not do the minimal local rebuilds, to use the packages from a project not affiliated with the CentOS project, has pretty effectively driven the CentOS core developers away from this mailing list

If a person doesn't like CentOS's pace and attention to shipping durable and 'correct' releases or with different features (as with EPEL), or want packages faster than CentOS' rate, PLEASE encourage them to either learn to show some minimal self-reliance in building, or to not use CentOS as a base
