[Steven Universe] Why don't other gems besides Amethyst shape-shift more often?

In Steven Universe we see Amethyst shape-shift quite often. Sometimes she does it for practical reasons like fighting or reaching high objects, sometimes she just does it to entertain herself or others. She clearly uses her shape-shifting powers very liberally. The other gems on the other hand pretty much never do. We see Steven do it every now and then, but he's still new at it and not very good, so it makes sense that he would be very conservative with it. We've seen Garnet do it once or twice at max. We have never seen Pearl or any other characters do it. Why though? We've seen from Amethyst that it can be an extremely effective tool for doing whatever you want, but she seems to be the only one that really takes advantage of it. Why don't the other gems on the show ever do it?

The question you should be asking is less why the others don't do it much, and more why Amethyst does it so often-- and the answer to that is because she's not always comfortable with herself and shapeshifting lets her be someone else when she needs to.
