In SR the mathematical model every observer is stationary w.r.t his FoR
and the speed of light is every which way = c.

That's right.. no ether mentioned or required for SR. It is ether agnostic.

SR, of course, is inconsistent with classical ether or emission theories ..
but they have been long since refuted (classical ether by MMX,

Correct

for example,
and and emission by Sagnac,

Completely wrong.

Try Page 9.

for example). SR is still concistent with the
mathematically equivalent LET .. but that does not mean SR requires LET's
ether assumptions to be correct

True, any alternative assumptions about what SR is physically describing
would be equally valid but in 100 years no one has come up with an
alternative to Lorentz's.

.. it simply would still work if LET's
ether assumptions were true.

Einstein objected to the asymmetry in the theoretical structure
of Lorentz's theory and avoided it by reproducing the maths without
any theoretical structure to go with it. He tried with his
"aether without the immobility of Lorentz's" but FAILED. In the end
his theory "puts forward no specific hypothesis" - his words.
