It seems like a pattern for languages that try to be more pragmatic. Instead of a Big Idea, turtles-upon-turtles approach that would take years to finalize in a form that doesn’t invalidate everything that came before it, one goes for an initially good enough approach and then release more and more features which to the insider might seem very holistic but to an outsider (like me) just sound like Static Runtime-Bounded Polyhydral Lambda Cube Type Capabilities and Associates.
