It's not a historical curiosity. The decisions needed to make an architecture viable on the long term happen early on and need to be sustained as code is being developed. A lot of that comes down to days structures used, system modules, abstractions, If that's done right, it's possible to make a good UX later. That's very hard in modern software processes which emphasize short term spirits.
