I think your example, i.e. the bridge construction, is actually addressed when the author discusses changes or update of the ‘implementation’ of a Tele vs the design of the Tele. He addresses the inclusion of noiseless pickups as an example of an implementation detail. I don’t think it is a stretch to include a modern construction six saddle bridge (although I think a term would veer towards changing design and not be an implementation detail).
