Then why don't you just use the automatic code splitting of CRA?? And it's not generic, if you ever worked on a years old code base you are happy if complexity is low. Do you know if all the page transition libs will play well with Next? They do not play well even with react-router, the standard React routing lib. Code can be more complex than you might think.
