In https://codereview.chromium.org/1632603002/ I've changed the default setter behavior for accessors installed using "SetNativeDataProperty" to do exactly that: replace the accessor with a data property. If you don't provide a setter yourself, you'll get that behavior. Lazy computed properties like you suggest can just call "set" on themselves and they'll be transformed to data properties.
Does that work?
