The Little Raven

There should a big section in the introduction to the PHB about how not all options (rules/races/classes/feats/items/skills/whatever) will be available to them depending on the tone of the DM's games. Then talk about a few examples... a DM wants a humans-only game for a more authentic S&S feel... the DM wants to run a Greyhawk game, so Dragonborn and Tieflings are out... a Good only campaign, so no warlocks... and so forth. Then, in the DMG, put a similar section about communicating with players about restrictions related to campaign themes and such. Discuss the pros and cons of limitations, as well as what happens when you go too far and make your players unhappy or even leave the game. Encourage both sides to be reasonable and communicative.
That is far better use of wordcount than slapping a rather arbitrary label that has no real teeth on various classes/races that will make people complain about how they're being dictated to and "who is WotC to be dictating to me what is common or uncommon in my game?"
