Loosely phrased, and wrong. The phase speed of light of a given
frequency
in diamond, water, air, any stationary medium, is constant with
respect to
the stationary medium.

Good enough to explain MMX.

So is SR, so is a fully-dragged Galilean ether, so is a Lorentz
ruler-shrinking clock-slowing ether, and so is just about any emission
theory.

Ordinarily, it would be somewhat pedantic point, but empirical
observations of the speed of light in a moving medium were historically
important, and continue to be theoretically important, in chosing which of
the above explanations of MMX could be correct. In the context of using an
emission theory to explain MMX, it's a worthwhile point.
