Yea, I was thinking something on the line of getPickItemResult or getPickItem but I'm not sure really what would work for the name could just stick to getPickResult but it seems like a confusing name to me I'm open to suggestions though!

I feel like I remember another PR adding a method for this but I might just be wrong. pickItem sounds fine

there was #10215 though that was related to the isPickable stuff which even though having the same name is basically something completely different
