Fair enough. It's a problem that probably doesn't need solving either, it was more so just a question of could it, but to your point, it's that barrier of entry that's stopping it, I would assume.
Ideally, a contender would replace all three with one new language. My question is more so why hasn't someone built a contender, but the answer to that is also quite clear.
