I think people like not having the usual Babel plugin/config + setup soup. There's value in all-in-one solutions with clear limitations. For example, TS doesn't implement JavaScript stuff below stage 2 while many devs liberally use stage-0 and stage-1 features with Babel. Some prefer TypeScript's way.

Totally. I tell new devs to use typescript. But I don't think using babel precludes shipping a binary with a standard pre-built config.
