The goal of lang features like these is to automate the optimization especially when it is hard to do at scale without it. Scenarios that start with "If only everyone..." are great candidates. Conversely, agreed, it's not THAT hard to convert an individual project, just being unable to handle third-party, so import-shaming some top projects can likely go far. Features that enable framework providers to empower others are great... And none is needed here. It's messy to push through type checking, but doable. Feel like we are reliving when js got a more static module system. A lot of kicking and screaming, and still issues, but a lot of good came out of that.
