Given that DSLs are hard, it does not follow that sticking "foundational concepts" into "components" is a better strategy than DSLs. If you write a DSL, you are standing on the shoulders of real giants. If you rely on components, you are going with the recently formed current conventional wisdom, and you are standing on the shoulders of relative peons.

Note that Fred Brooks argues for conceptual integrity, provided by a single human being, as the most important guarantee of product quality. If you use components, then you are accepting a system partitioning that has been decided many layers above you. If you design languages, then you cut out most of those layers. This gives you far more control over product quality.

Yeah, it's hard. Quality is hard. If your primary goal is anything other than quality, you will probably not produce a product with much of it. That's the real reason why there's no silver bullet.
