Would unit testing components be of value to the project? It doesn't appear that anyone is pursuing testing too much, maybe that would be a good place for me to be productive? Negatives is it will slow down our CI build and as things change it will slow down PRs, but we could do the component testing separately and eventually streamline it into the CI, so we don't have those kind of project flow problems, until things are more stable.
