--- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> ---
it is not mandatory (for C++20 compliance) that the implementation provides
symmetric transfer - so it could be switched off - or XFAILed. 

However, users state that an impl. that can't do the symmetric transfers is not
useful in a number of important applications.
