The main issue I see is that our fork is diverging from the main repository in ways that are not (or probably not) backwards compatible for existing users of puffing-billy, which would mean we will become the maintainers of our fork perpetually if we are not able to get our changes merged into the main line.  I don't particularly see the changes in this PR being at issue; rather, some of the other changes, especially removing the port from the URL could pose a major compatibility issue.
