Hi @fabioberger, thanks for writing this up, this makes very much sense!

Implementation Notes

(Trivial) confirm if one is looking at current package.json state that the library is currently not using babel.

We have done this a couple of time lately (one can just do an organization-wide "babel" search), here is one example for inspiration for an implementation.

Preferred way is to have this build to a dist folder which is not included within git for consistency reasons but created before npm publication.

Between conclusion from other implementations though is that this field of topic creates different new challenges regarding the structure of repos and should be handled with some care, especially content of a potentially-distributed package should be pre-checked carefully.

In the case of this library there is probably the bin directory which should be taken an eye upon.
