[Fedora-packaging] Re: DNF: "There are following alternatives to this package"

Hi! We'd like to propose a new functionality for dnf: When a user tries to install a package XYZ and dnf doesn't find it, dnf would recommend them alternative packages. These offered packages would advertise that they are an alternative for XYZ using a specially formatted Provides tag.

For example, packages `python2-requests` and `python3-requests` would both have the following tag:

Provides: alternative-for(python-requests) = %{version}-%{release}

You could probably achieve that behavior with normal provides we have today and a DNF plugin.

Just guessing. And people who care for such a feature could just get the plugin, you know...
