Fair enough! True, Babel is only "core" for a subset of JS developers, not for the language.
I don't really despise anyone in Babel, though, I'm only criticising their packaging method. Babel isn't doing the million-packages thing to gain popularity.

Babel is not core JS infrastructure. It may be close to fundamental to the modern NodeJS development experience, but JS exists happily (and capably) without any of that stuff (including package.json, for that matter).
