This is a touring bike trick, and touring bikes usually have mountain bike derailleurs. MTB derailleurs have some extra capacity for a trick like this because their tooth and wrap ratings take into account the possibility of rear suspension changing the geometry. GRX probably doesn't have this fudge factor built in, or at least I wouldn't count on it as much.
