You're misreading my email in that case.

No, there is no official word from the OpenGL ES working group at the
present time regarding the incorporation of MRTs or any other
functionality in any hypothetical future release of any API or
hardware. I'm sorry that I can't be more clear, but members of the
WebGL WG are privy to information that we can not share publicly.

In a public capacity, I think it is acceptable for WebGL WG members to
guide the introduction of WebGL extensions in a way that seems that it
would not contradict potential future directions of mobile hardware.
For example, by examining the existing OpenGL 4.2 Core Profile spec,
or extensions already proposed against OpenGL ES 2.0.
