Somewhere inside Disney, the motivation has changed. The use of Imagineers' names, for the most part, were originally not so much about recognition and promotion, but layering an experience. Names on the gravestones in the Haunted Mansion was to have some personal fun while filling the need of a tombstone to have a name. Now it's about marketing "secrets" to fans who like to feel superior because they're "in the know." What was once merely part of the design experience is now more and more part of the marketing package.
