I think it would, for a number of reasons. First, it’s a little sacrifice that lets us see they are serious about their new browser, and not just changing the name. Second, it puts pressure on them to implement demanded features, since people can just fork the browser otherwise, as it happens with Chromium and Firefox. Third, it’s good for security and interoperability.
I’m also curious about the modularity of their code; mainstream open-source browsers don’t excel at this AFAIK.
