I am fine with it being downplayed but how would spells like detect alignment, protection from evil, and alignment restricted items work?
I don't think Detect Alignment is a spell anymore.
Protection from Evil has been changed to "Protection from Evil and Good" and grants its bonuses vs aberrations, celestials, elementals, fey, fiends, and undead.
Alignment restricted items seem rare, but do exist. For example, a Talisman of Pure Good states "A creature that is neither good nor evil in Alignment takes 6d6 radiant damage upon touching the talisman. An evil creature takes 8d6 radiant damage upon touching the talisman."
