In https://github.com/mkalkbrenner/ddev-solr/blob/main/docker-compose.solr.yaml there are many comments that refer to other versions of the file, which are irrelevant, since this is the one being used. Could you please update the commentary there and remove things that aren't relevant? Linking to variants would be fine but I don't think it's necessary.
In general, with an add-on, people won't be editing anything (or knowing anything about other variants)
