I was going to point you to the Pure series of roms by Beanstown, but I don't understand your question... You don't want ANY custom stuff at all or features, then what's the point? Just install stock android...?
I don't understand this sentence. Google only has a single phone that has only been out for like 1 day now, the Pixel. And it's not even stock Android, it's got extra features that the stock Nougat doesn't have. Again though, I think this whole thing is moot, because lots of phones have roms on xda that is basically just stock android with no customizations, so just install that and be done with it.
I said Google-branded, not Google-manufactured. The Nexus line is what people typically understand by "stock Android".
The point isn't that there are no vanilla AOSP ROMs for most devices. The point is that they usually suck, and a reputable well-supported one that actually worked properly would be a massive innovation.
When people say "Google's phones" it is generally understood to mean the unlocked line of Nexus devices that they sell directly and provide updates/firmware images for directly.
