I also do not see compelling reason to provide a compat symbol this
specific issue.  The destruction handles are registered only with
__cxa_thread_atexit_impl and it is used only for thread_local on
C++.  And C++ definition on quick_exit stated that it does not
run the TLS destructors, so a program that relies on it is just
expecting a non-conforming implementation behaviour.
