The low number of available vertex shader uniform vectors is the most surprising restriction to me, and probably the hardest to work with.

Having access to only 128 uniform vectors implies that GPU skinning is severely limited to a small number of bone transforms. It would make a world of difference if at least 250 uniform vectors were supported on most iOS devices. As you can see on the WebGL stats page, 99.6% of WebGL enabled browsers support at least 250, so it's become a reliable vector count to use.
