There's two "layers" here: the higher layer is whether the maintainer is
actually maintaining the packages. Obviously, maintainers occasionally stop
maintaining packages at random points in time, and no amount of formal
EOL dates and rules will change that. Hopefully, other maintainers
will step in. A second lower layer is how we inform users about the
package status (obsoletion, retirement, ...). We need to make sure
that the mechanisms we introduce in this lower layer do not make it
impossible to follow our packaging guidelines even before we get to
the soft upper layer.
I think we should (do?) handle it in the following way:
if the module EOL is before a given Fedora version goes EOL, it should
never be proposed for installation in that Fedora version. In other words,
if foo:3.15 stream has EOL of 1/4/2020, it should be shown in
'dnf module list' in F<=31, but not F>=32.

Yeah, retrofitting fixed EOL dates onto Fedora is a form of self-flagellation.
My understanding of current policy is that it would not be permitted
to have such a module in current fedora. It could only be included
in a version of fedora where it will receive updates for the entire
life cycle of that Fedora version.
Exactly. The question is whether this happens like this, or not.
I scanned https://docs.fedoraproject.org/en-US/modularity
, but I don't see
any mention of that.
