I would love to support Solr 9.x, and I am happy to do the release work and branch setup etc. But we need someone willing to figure out what changed between 8.x and 9.x and make the appropriate changes to the code. I've got limited time these days so perhaps we can collaborate? I'll set up the 9.x plugin branch if you would like to research the API changes.
