Oh, sure. Anything experimental seems fine here. But I wouldn't really
expect to start threading such an attribute's semantics through the trunk
optimizer... If there was some need to keep an attribute clearly marked
"experimental" for a time in trunk until it settled, that also seems not
unreasonable. But I don't think that's the situation we're in here.
