While for some the windows of Main Street, USA have become a prominent part of the experience, they were not deliberately designed to be as such, whereas that appears to be the case with Buena Vista Street. The use of names was once a secret, intended to help populate the space while also giving credit to those involved. The names being associated with Buena Vista Street have no overriding connection to its design or the history of Los Angeles.
I also think the "nods" to Disney history have become excessive in recent years. When it opened a lot of Disney's California Adventure was intended to appeal to those who typically dislike theme parks and the notion of being an "outsider" and a little "anti-Disney" was acceptable within Disney. Not resonating with guests, and not looking good for the brand, being vaguely public about such views is no longer in fashion and all of these "nods" come across to me as heavy handed attempts by those involved to show that they too are Disney fans. So much of the remodeling seems to be to be a reaction to the park's initial strays from the "Disney way" but it has been guided by people who ultimately see Parks and Resorts as an extension of marketing and not one of their powerful storytelling mediums.
