I'll try to remeber this point for the next iteration...

IMHO, it should check the number of handles in the handle-area via the
TPM2_GetCapability() call. If a vendor is ignorant enough to put a handle into
the parameter-section, there is nothing we can do besides some quirks once we
recognize them...
But this will be the same for all OSes...

Cheers,
Andreas
