tracking-ISSUE-109: siteSpecificTrackingExceptions property has fingerprinting risks: is it necessary? [Tracking Preference Expression (DNT)]

The siteSpecificTrackingExceptions list property (for JavaScript querying of existing site-specific exceptions) enables even easier fingerprinting by any first or third party JavaScript. Could first parties instead rely on calling requestSiteSpecificTrackingException and receiving a true response if exceptions have already been granted?
