It doesn't say anything. I doubt there would be any way to add sufficient
description of them to the standard in less than 5 years for this feature to
have a meaningful description. So this incredibly niche feature would be
standardised as "it is implementation defined whether this intercepts
anything". Which in turn means implementors can simply ignore the feature
because intercepting nothing is Standards compliant.
