Can you please add something to etc/PROBLEMS about this issue?

How widely is this mechanism used in the wild?  If it is used widely
enough, perhaps we should tell people not to build with XInput2 if
they have vested interests in those methods?

Also, maybe submitting bug reports to the respective developers would
cause them to improve the situation?
