Say, rather, that no successful theory has ever been discovered with both a
reasonable domain and an aether, while SR and GR, which have no aether, have
large domains and are very successful. We can never know for certain whether an
aether exists, but we do know that our best models don't have it.

That's like trying to say "blue is true" -- both attempt to use the relation
"is" to relate two completely incommensurate concepts. Relativity is a theory of
physics, and "true" does not apply to physical theories -- we can never know how
nature "actually works". The best we can do is construct models of the world,
and determine their domains of applicability via experiments, and successively
improve the models and increase their domains -- this is called science.
We KNOW that GR is incomplete, and that its domain does not include phenomena at
sub-microscopic scales (e.g. the quantum processes in atoms). SR is merely the
local limit of GR, so GR is the proper theory to represent "relativity" here.
