I selected "other."
I permit mostly everything, but that has nothing to do with
WotC telling me what is or is not "core." I'm pretty sure that the "everything is core" slogan was just a quippy way of stating that all released classes and races will receive ongoing support and be included, or at least not excluded, in all settings. The statement was of course made in context of
3e's policy, which was to very rarely support classes and races from non core books (although this policy was eased later in
3e's lifetime).
I simply read it as stating something like, "Remember how we made the Hexblade, and then never released a single new thing for it except one article in Dragon, and then a few spells and a few magic items years later? We're not doing that anymore."
And yet another word from our sponsors
