On play store you can see the permissions that an app uses and they are grouped by category. Have full network access is set in the "others" category, same as notifications and vibration. This is a category where (supposedly) permissions are automatically granted.

But to be honest, other similar dangerous permissions like "view network connections" and "receive data from internet" are also there, categories are for "camera", "microphone" etc.

I suppose that the average user is more concerned about specific features, and since basically almost all apps require internet it may be there to avoid noise. Still, an "internet" category would have been nice...

The reason why internet access/downloading from the internet isn't a "major" permission is that asking about it would let people conveniently disable it for any offline apps with ads in them to remove the ads. Google doesn't like that, obviously. Of course, you can still disable your wifi/mobile data connection entirely, but it has friction that most average consumers won't trouble themselves with. But if the app asked if you wanted to give it internet access on launch, Google's ad revenue would probably be visibly affected.
