Many objects in the DOM implement custom name getters (for instance
NodeList) and a few even implement custom name setters
(CSSStyleDeclaration, at least the way it is done in WebKit) but no
one has clamored for a custom deleter or expected delete to work "as a
matter of consistency" or been confused that "style.opacity = 0" is
allowed but "delete style.opacity" is not. So I would say the
available evidence argues against your conclusions.
