Yeah, but there's a selection bias present in most feedback like this, isn't there? People are more motivated to submit feedback when something annoys them. This is speaking as someone who is also annoyed by AI features.
That's a slightly different question, but an important one: the presence of a group criticizing a feature doesn't mean the absence of a different group requesting it!
When Mozilla initially made the Connect forums, it was to solicit requests for new features. I can't stress enough how few people joined the forum to request more AI in their browser.
