All theories are approximate. Classical mechanics is approximate, although
it was thought exact and final before ~1900, and is used most of the time
since then, so what? A theory must describe all the known facts. QM and GR
can't alone, therefore they aren't theories. QM + GR is one, but it is
mathematically incoherent. Some persons have difficulties to tell the
difference between physics and mathematics, that's all.

It is precisely because he don't that we have this debate. Poincaré *never*
wrote down his postulates in an unambiguous and workable way. If not,
please answer my challenge, quote him and work out the purported "Poincaré
theory".

Einstein didn't rejected all the postulates used by non-relativistic
mechanics, that's not the issue at all. What is important is the new
principles he introduced and made clear, without which special relativity
doesn't work, and the hidden assumption he identified and dispelled. This
great discovery doesn't deserve this nitpicking.

Well, let's say you are right, but nevertheless entirely unconvincing.
