I did last year when flying from MAN in LH Y since I was travelling with a bandaged wrist and was concerned about having to go through a crowded security check in a hurry. (Plus bad previous security experiences at MAN where I'd almost missed a flight.)
It worked since I was through in 5 minutes even with an extra check of the bandages, and I was offered help lifting my bag as well. But a friend on the same flight said that regular security was very quick that day, so who knows if it was actually necessary. Certainly felt easier, though.
