Is it though? By default respec is not fully possible in Pillars of Eternity, Cyberpunk 2099, Path of Exile, Pathfidner: Kingmaker, etc.
The only recent RPGs nowadays with lasize faire respec was Divinity Original Sin 2 and The Witcher 3, IIRC.
Saying it is "standard" when many current and recent RPGs do not have that option in full or part is not really correct.
