automatically import missing packages

All I want to see is a way for Unity to detect missing scripts, based on the metadata from assets, and import those.

A perfect example of this is probuidler. Exporting a package with probuilder scenes won't export probuilder scripts with it, and importing those packages, won't import probuidler with them either.

Infact, the prefabs will display empty.

When the errors are checked, the editor tells you that probuilder is missing, and even provides the UID for that version of probuilder, but you are on your own to go back to package manager and install it.

So, any time importing a package, I want Unity to check for package dependencies that exist as components of the package manager, and provide the user the option of importing those packages to support the full set of assets being imported into the project. Not just for probuilder, but all builtin scripts available form the package manager.
