I think the main problem with the architecture astronauts is that they are trying to nuke a cockroach.
In other words, they are trying to find an overly wide and generic solution while all they have is a specific instance of a problem in a particular implementation they need to design for.
Yes. Solving the generic problem is usually much harder than an actual problem. Only try to solve the generic problem if you really think that there are huge benefits of it, and really know what you do, and you can take huge risks. (Like creating MS Excel instead of creating a special accounting software.)
