@xtuc There are also JSX builders, so it is.

@nicolo-ribaudo good point, i've been flying across that PR and haven't seen them.

This is a breaking change, I don't think we can land this in Babel 7. What about warning and removing it in Babel 8?

Well, in Babel 7 we already made different breaking changes in pre releases

We can definetely land a breaking change in the beta, just need to add a changelog entry and add this to the list of things to codemod

lgtm then.

Actually http://babeljs.io/blog/2017/03/01/upgrade-to-babel-7-for-tool-authors#ast-changes-jsx-and-ts-node-builders-from-babel-types-package-renamed

I'm for making this change in 8.x. If it was just TS it'd be fine, but since it's essentially a meaningless breaking change for JSX, I'd rather leave it, encourage people to transition during 7.x's lifetime, and remove it in 8.x.

If we want to special-case this PR to just drop it for TS that'd be fine with me.

Alright, I'm ok with that
