IMHO pip-type Sage packages should be limited to a) when we need a specific version or b) when it is required as a dependency.
Whatever the official user-facing installation command is (i.e. "sage -i" right now) should just fall back to pip/PyPI when there is no specific package in Sage. Ideally it will behave like dnf/yum/apt/... and 1. Display what will be installed (including dependencies, free/nonfree license information, package type, ...) 2. Ask whether that was intended (y/N) unless overridden with a commandline switch "-y" 3.
