It's pretty simple that Einstein combined his theories
of GR and SR into a theory "Relativity", with GR governing
SR not the other way around, and: that the L-principle,
for light's speed constancy, is a precept of SR, and, Relativity.

The "no absolute motion" bit, or "Relativity", doesn't address
itself neither the Galilean linear or gyroscopic rotational
space-contraction, the one going out the other in, nor does
it address "absolute space", nor "absolute time".
