> GitHub has been useful to store all repositories of the Dillo project, as well as to run the CI workflows for platforms in which I don't have a machine available (like Windows, Mac OS or some BSDs).

The post does not mention CI anywhere else, are they doing anything with it, keeping it on GitHub, or getting rid of it?

That sounds like a bad approach to developing a Web browser, surely it would be better to make Dillo correctly work with the default cgit CSS (which is used by countless projects)?
