Oh good point, the 1× ones are rated up to 42T. I've bodged an 11-42T in a 36T SRAM 10-speed derailleur before though, they come with really long B-screws.
I will leave it @PhilDAS to decide, if you want that GX 2×10 I won't bid on it
Depends which cassette you're using. I'd stick with the old 2×10 RD if your biggest sprocket is 36T
