Sure. It's technically possible for me to re-make Mozilla's infrastructure with a great effort. But what I mean is, Mozilla doesn't want to provide support (like security updates) or services for their browser unless they completely control it. Probably the argument is that this prevents ignorant users from accidentally downloading unbranded and accidentally installing some malware extension and blaming FF brand for it. But it's about branding and perception far more that security or resources.
