I'd argue that fact checking can be more important today than anything that you've mentioned. Modern problems require modern solutions and it's natural that browsers extend their feature sets. I'd agree with you had they announced that they were planning to merge Firefox and Thunderbird.
Each step reduces the amount of users who could use the feature. If they think this feature is important, it makes sense to include it with the browser.

I think it would be fine as an official extension. Shipping it built-in feels weird to me.

I agree that fact checking is important, but disagree it should be a core function of a web browser.
I think you mean a web curator. Browsing is dangerous!
Bloat goes in extensions.
Do you suppose there are any dangers to fact checking as a practice?
This is just bloatware. An extension is the place for stuff not everyone will need or use.
