Sorry for the confusion with work that is already done,
We can drop the critpath thanks Adam!
As it goes for EoL and package retirement we for the past few releases we are saving EOL date in bodhi.
So getting EOL for specific release is not a problem once the release is out.
For storing the orphaning reason and other potential metadata. We can store some of it in git in form of notes on branches not necessarily in pagure-disgit specific code-base.
With toddlers i think the path is clear we need to use bodhi as a source of truth about releases.
Similar work as on toddlers will need to be done on mdapi
For the compose metadata we can store the the json blobs on fedorapeople for now and search for some stable place.

In the pkgdb time, the EOL status was basically simply computed from the release
status, ie: what we still have at: https://admin.fedoraproject.org/pkgdb/api/collections
(looks like we should fix the branchname in that json)
but we could just go back to this :)
