I was tracking a TODO file for the remaining tasks. And after the recent setback of expectations reported above I have entered testing and found quite a list of things that should be tackled before going to the NEW queue with this.
If you are curious, feel free to have a look and tackle any of [1]. But since at least some seem to reflect the package upstream repo getting outdated (again) I'm not yet too confident in continuing on this. Either way, documenting this in the repo and the ITP is an important step.
