Since we're replacing Travis with the new Github Actions workflows, you'll also want to delete the .travis.yml file and the [![Build Status](https://travis-ci.org... bit that references the Travis build in the README.md file.

I think this is okay to merge as-is, but I'm noting that there's no deploy workflow (which there wasn't in the Travis configs either). @p-galligan can you put adding that workflow on your to-do list? This should deploy to PyPI, probably when we cut a release (or whatever our general pattern is for deploying to PyPI).

Following up here as well that I a python publish workflow already exists for this repo.
