No.
Veils explicitly is not an SLA, calling it such is a house rule and not an assumption.
Like a Barbarian's Illiteracy, Bard's Bardic Knowledge, Cleric's Bonus Languages, Paladin's Code of Conduct, Rogue's Trapfinding, and of course all Class-granted Spellcasting. These are untyped traits best classified as simply "Class Features". Which is exactly the role of Veils is to Wardings. There is a premise there, can you see it?
