I've hired (and like to think I'm part of this group) folks that can comfortably pick up any domain, not just a language or framework. That's to say, if I needed them to get depth on compiler back-ends because that was part of our value proposition, they could quickly get up to speed on the state of the art and be productive. Maybe they'd start by reading through LLVM documentation and code, understanding its optimizations, and then catch up on the latest papers? Who knows, but they'd have some confidence in weeks. Would they be on par with world class experts? No. And I don't think the OP claimed this, but not being limited by languages and frameworks isn't that rare.
