Basically, the ES group interpreted the line differently than the desktop
group.  There was discussion about this while bringing arrays-of-arrays to ES,
and that precipitated the clarification in the desktop spec.

Frankly, unless there is a conformance test or a dEQP test that requires the
restricted behavior, I'd rather not start enforcing it.  Since the code is
already landed, it's probably not worth the effort to undo it.  My best guess
is that we should just remove the gles3 tests that require out-of-spec
behavior.

Also... if a patch series is known to cause a big pile of tests to fail (you
did run piglit before pushing, right?), that needs to be resolved first.
