Ehh, I assure you if we don't change it... Fedora 11 will still ship so it
doesn't "have to change".  So someone needs to articulate, very precisely,
what benefit investing time into our buildsystem, testing, release
upgrading (Fedora is more expensive then RHEL), etc is going to have.
Keep in mind we still can't even build epel on our normal buildsystem yet
because of $PEOPLE_TIME

What benefit will it have to our users?

What benefit will it have to our developers?
