@544fb7bb @365a528d hmm, it would break for a newly developed package that defaults to esm while developing, after publish and import into a project that uses an old node version? 

 @365a528d @544fb7bb so this does not affect files inside node_modules, so it won't break every npm package everywhere? 

 @4254ca2a I'm in Madrid now, for the first time. It's beautiful here!
