When would I want to use JSR? The "Why JSR?" section simply says JSR is a superset of NPM that can be used with any javascript package manager. But NPM itself can also be used with any javascript package manager as far as I know. It seems like the benefit they're trying to add is strict type support for packages, but the fact that it's a superset of NPM means all existing packages that lack types are still supported by JSR. So, what benefit is so great that it's worth segmenting the ecosystem?
Side rant: not at all a fan of the decision to punish libraries ("slow types") that use type inference by reducing their score.
