Hi Kurt, your assumptions are correct. GeoTools 19 is out of support and no longer being released, if you want to contribute you'd have to start with a pull request with changes and tests on the master branch (version 22-SNAPSHOT) and then eventually backport to 21.x and 20.x (those are the branches currently alive, and until September).
