Imo this extends to chromium too. Google owns the source code and can pull it whenever they want. Sure, chromium browsers might be able to putter along for a little bit, but my understanding is that the reason why we're now at Chrome/Chromium vs Firefox vs Safari is because Google shits out so many new """standards""" and "features" that you need a large team to keep up. It's supposedly why browsers like Opera switched to using chromium instead of trying to maintain their own source code.
This is a feature, not a bug.
