The idea that "terminal wizards" reject this is rather undermined by the fact that "terminal wizards" made open and close double quotation marks accessible as simply [Group2]+[B04] and [Group2]+[B05] on an ISO 9995-3 conformant keyboard.

Or [Shift]+[Option] [B04] and [Shift]+[Option] [B05] if there's no explicit [Group2] shift.

Open and close single quotation marks use the same keys.

"terminal wizards" have done quite the opposite of rejecting this.
