It's surprising if WebKit uses a 16 bit depth buffer when a 24 bit buffer is available. I try to get the widest depth buffer available. Can you post a WebKit bug and include the test case you're using to tell that WebKit is choosing a 16 bit depth buffer?

I am certainly for adding OES_depth24. I agree that it's pretty universally available, especially with the new generation of chips we're seeing now.
