Strictly speaking it does, in media, more strictly speaking doesn't look for the light in media as if it's slower.
We could add that m isn't static either and that in the useful undergrad formulation you got multiple terms, and we got a ton of useful results from that equation.
Light energy, yeah the cones it creates and the symmetry between dimensions of space and time are kinda rad and already without going deeper something akin to matter energy light equivalence for not exact meanings.
But if one would argue with them the best way would be to not argue but post ppb
