I'm curious why does next.js need to maintain a list of polyfills in the first place? Isn't this something which would be handled automatically by babel? Sorry if this is a n00b question... I'm very new to web development and would like to understand a bit more deeply the gotchas around using modern JS features in my code and still be supported on older browsers. For example are there are any other missing polyfills besides Array.at?

Probably so they could version control them instead of debugging other people's babel config problems forever.
