I wonder how long it’ll be before this becomes the primary treatment. I sure know that I’d prefer this over the other options even if the odd were slightly worse

That good! Now you also need to find something you want to fix or improve :)

Find something wrong or something you think could be improved. Check if it’s a raised issue or on a roadmap. If not, raise the issue. Fork the repo, fix the issue, make a pull request.

Github is probably the most accessible for doing this, create an account and learn the basics.
