you might be better off just having a VTPM_PROXY_IO_ENABLE_FEATURE
.feature = LOCALITY

If that fails then the feature is not supported, no real need for the
query in that case.

Not sure about Jarkko's point on request/release locality.. Is there a
scenario where the emulator should fail the request locality?
