Core extensions missing

It says here, that there are a host of Core payment methods included in any installation of Openart 4: http://docs.opencart.com/en-gb/extension/payment/
But when I look under Extensions->Choose the extension type->Payments in my fresh Opencart 4 installation, I only find "Bank Transfer", "Cheque / Money Order", "Cash On Delivery", "Free Checkout" and "PayPal Commerce Platform".
What am I doing wrong?

All extensions except those you are mentioning are removed with v.4.x
The docs are valid for v.2.x and 3.x only.

If you need any other extension, please get 'em from the OpenCart Marketplace
