Newton's optics was abandoned, if not in XVIIIth

And recovered by Einstein in 1911, with a paper WHERE HE MAKE
AFFIRMATIONS about gravitational mass of energy.
 
Ask yourself WHY 1960 Pound-Rebka paper had the title "Apparent weight
of photons" and later, before his death, Pound wrote his memoirs
"Weighting photons".

All entirely correct,
-in the Newtonian approximation to general relativity-.

As yet we have not yet encountered circumstances in which
the Newtonian approximation is not good enough
to calculate the relativistic red shift,
