There's a big difference. It's about empowering players and DMs, as opposed giving carte-blanche to the publishers to put in every piece of rubbish.A difference without distinction. The point is Eberron is designed to allow anything the DM wants to allow and no idea is strictly forbidden because of The Lore. That is an exact contrast to settings like Dark Sun and Dragonlance which banned stuff for the sake of banning it and still creates arguments if things created after the original publication date should be allowed or not. Eberron sidesteps all that with one elegant phrase, though I am not surprised somehow Eberron purists exist to delegitimize anything that came out after ECS...
As for Keith, I highly value his opinion but he is not the Voice of God. He reminds everyone of that when he says "In MY Eberron" as a way to say his is only one of the many ways to interpret Eberron.
So a player asks "can i play a tabaxi" and the answer is "maybe, let's see how we can fulfill your desire in a way that makes sense" as opposed to WoTC publications just having tabaxi suddenly showing up everywhere.
