For sure you're right, it's always a tradeoff. But to compensate for a deficit in popularity, a technology needs to have tremendous merits. Language performance is only important in some very specific cases (I/O trumps CPU in most use case), type safety is now becoming pretty standard everywhere. Your example of embedded system is indeed a case where the environment has so specific constraints that the runtime behavior of the technology can make a huge difference. But for the regular "json <-> postgres" backend that are the bread and butter of our industry, i'd say it's an exception.
