If you really want to blow your mind: Are any of the rules in Dragon Magazine
"legal?" If they're optional rules, then the races they publish don't count as stealth errata, just variants. If they're not optional rules, then you run into the unpleasant situation of players showing up at the game bearing rules that the DM has never even seen before, and might not approve of.
Personally, I never use the term "legal." It sounds silly to me, like the D&D Police are going to come arrest you if you play a bugbear, or like the Supreme Court has ruled that DMs must allow every item from Adventurer's Vault now matter how game-breaking. (Reading glasses are only level 2???) Instead, I tend to think in terms of RAW vs. House Rules, because the term RAW (Rules As Written) is much clearer to me.
