I have no idea, I don't have experience with Babel. As mentioned in the release notes, this change makes TS conform more closely to ECMAScript, so I don't think it's a bad decision. But it would've been nice to get some warning or error when trying to stub an ES import, rather than the silent failures

Have you found a way around that change? It’s blocked me from upgrading as well.
