Eh, I think the text we've discussed so far is enough for any reasonable AHJ or jurist to conclude that "Class A" means "UL 489 Class A".Nothing in a informational note would be admissible as enforceable in court. The term Class A is probably also unenforceable.
Regardless, in the 2023 NEC 210.8 was changed to require a "listed device". And the definition of "listed" refers to the "appropriate designated standards". Between that and the allowances of Article 90 and also 110.2 which requires equipment to be "approved", any AHJ is on safe ground requiring GFCIs to be UL 489 Class A. As they will do.
