Well, from the very beginning I have been not very happy with
the introduction of this, and I still consider it half way acceptable
only because of not seeing any good alternative. If we look at
it strictly, it's in violation of the rule we set forth after XSA-77:
No introduction of new code making the system susceptible to
bad (malicious) tool stack behavior, and hence we should reject
it. Yet that would leave XenGT in a state where it would have no
perspective of ever getting merged, which doesn't seem very
desirable either.
