I haven't looked into the chatbot thingy at all yet, but if it meets basic quality standards (local LLM, not too large in size, actually helpful), then personally, I do actually think that it should be included by default, because it'll primarily help out the kind of users who don't know to install add-ons.

Like, people had the same complaint with the translation feature they included, and I'm just seeing my dad who doesn't speak English, who would never hear of such an add-on, where this just opens up a big chunk of the web to him.
