Remove default drop shadows on caption text

I started using the caption text shape feature for the first time, and couldn't figure out why my caption text kept showing drop shadows (since I didn't enable drop shadows). I finally figured out that this is a default setting for caption text. I would recommend removing default drop-shadows on caption text, and would argue that most designers do not use this feature (though I'm happy to be proven wrong). Drop shadows on text have a generally dated feel, and should be something that designers opt into, rather than out of.
