not to mention that google still controls the chrome extension marketplace, and will stop accepting mv2 extensions by the end of the year. So not only do you have to maintain the mv2 related code, and keep reintegrating it whenever google moves a bunch of code around (which from what I hear they do quite aggressively) or hard fork, you also need to maintain your own repository of browser extensions, and get developers to actually develop them for your browser specifically, rather than just for chrome, too.
