Any way to move "The following packages did not export their `package.json`" warning to onwarn?

Getting the “The following packages did not export their package.json” warning importing a package. I requested a PR for that package and owner closed it saying bundlers should use fs to read the package.json instead.

Regardless of the owner being right or not, is there any reason why this one has to be done with console.warn and not part of onwarn warnings? All warnings should be suppressible so users can suppress them once they see it and deemed not important.

I’m ok with rollup-plugin-svelte not trying to do more to handle other packages not exporting their package.json. I guess all I would be looking for is some configuration (e.g. in rollup.config.js) where we can list the libraries to skip the warning for. Essentially a way to say “yep, I’ve seen the warning. Now stop showing it to me for this library” 😃

We will probably remove pkg.svelte which will end up solving this. However, we’ll need to introduce a warning about the upcoming behavior change for a period of time first for packages where that would change how the package is resolved.
