I’m orphaning the package python-markdown-include[1]. It is a leaf package in Fedora and EPEL9, and has been for several releases, although it is still used by a number of packages in the wider Python ecosystem[2].
The package is up to date, upstream remains active, and the spec file is clean, trivial, and follows modern practices. I’m not going to keep maintaining it “just in case” any longer, but feel free to pick it up if you think you will need it for something.
