If the only options are "full access to everything" or "no access at all" then users are going to pick the former every time, because there's no alternative. And worse, they'll get used to extensions requiring "full access to everything" and become more likely to approve that permission even for malicious extensions. That's essentially the situation for lots of extensions prior to manifest v3 (and arguably post-v3 too, but it's a step in the right direction). Fine-grained permissions are a good thing, even though they do unfortunately make things more challenging for developers.
