Sure. But the field looked a lot different in 2000 than today, and the weight of each of these have shifted vastly along with different hypes, trends, the introduction of cloud providers etc.

Microservices in particular is often decided at such an early stage and on such loose ground that in many cases it can barely be called an intentional software design, but rather something more akin to picking a perceived one-size-fits-all template. But it does then certainly leak into everything else - completely unnecessary or not. Which is why I'm asking that question.
