According to the product specialist

Pros
Thanks to this derailleur you can use a larger cassette and so cycle at a smoother pace.
This derailleur has an industrial look.
This derailleur can only be used with a single front chainring.
The Shimano GRX 11 speed rear derailleur can be combined with Shimano 105, Ultegra and Dura Ace 11 speed groups.
Thanks to the extra tight spring tension on the cage, the derailleur won't rattle on bad or unpaved roads.
Ideal for long rides on cobblestones, when a road bike rear derailleur falls short sometimes.
A long cage (GS) is compatible with these cassette ratios: 11/28, 11/30, 11/32, 11/34.
Easily adjustable with its adjusting screws and cable adjusting screw.
Cons
This derailleur can only be used with a single front chainring.
This derailleur isn't compatible with cassettes with a smaller ratio than 11/30.
