There might be a disconnect, but I think it's probably not in the direction you expect.
The vast majority of high-performing engineering teams (good startups, big tech companies) don't hire standard SWEs for specific language/framework expertise. The truth absolutely is that languages are interoperable enough that someone who is smart and understand the underlying principles can get up to speed in a new ecosystem quickly.
