I suspect this is as culturally determined as the differing American, European, and Japanese attitudes to rebuilding buildings. European cities typically retain medieval street layout and as many buildings from that time as possible, sometimes even rebuilding to the original style after destructive events. Whereas Japanese houses have a ~30 year lifespan and are routinely rebuilt. And I'm looking up the hill at a castle that accreted between the 12th and 17th centuries.

Just as the street layout will outlive the buildings, APIs tend to be extremely durable and intolerant of destructive rewrites. Consider the Python transition.
