I'm going to mark this as not a bug, since you were able to get the desired behavior by configuration.
As for why CoreFilter isn't in the default filters, these types of items are part of an ongoing effort in the community to make OpenStack better for operators. The program facilitates communication between operators and developers so any issues with running OpenStack can be addressed. Please see the following links on how you can join this effort, get answers, and bring about changes that are important to you. This blog post [1] should give you the information you need to get started, by signing up for the openstack-operators mailing list and checking out prior discussions captured in the etherpad (one of them is "Reasonable Defaults"). I hope this helps.
