Oh I realize they will still ask but now they don't have the argument that the admins are in control and can change things. We can simply quote the page reference in SHE to prove it's a wotc decision (since th3y never took the admins word for it before)
I should also note that XGE includes a section in the book on PHB+1 specifically, and even "strongly suggests" DMs adopt this rule in their home games. This is the final nail in the coffin on the endless threads requesting the removal/modification of the PHB+1 rule.
