This is revealed by the new Intel documentation on USB 4, where they plan to release the USB4 driver in three versions: 0x9A1B, 0x9A1D and 0x9A13; and neither of them would be compatible with full-size USB A ports.
USB 3.2: the minimum specification of future Intel ports
The leak, which appeared earlier in the week, indicates that USB4 has support for USB 3.2, but not for USB 2.0 or USB 1.1. Thus, everything seems to indicate that Intel is not going to force computer manufacturers to launch laptops or motherboards that have USB Type A ports if they have USB4 connectors.

As we see in the image, it is only offered USB 4.0 and USB 3.2 compatibility, which are only available for USB C connectors. In the company’s current chipset drivers, USB 3.2 and USB 2.0 are mentioned as compatible, but they no longer appear on the new one. This would imply that future laptops might not come with full-size USB ports, and if you want to use any device with USB 1.1, USB 2.0, or any other that has full-size USB, you will need an adapter or a dongle.
Manufacturers have alternatives to continue including USB A
Apple was the first manufacturer to launch a computer that did not carry any USB A port. Most current ultrabooks do, some having just enough thickness to include it and not forcing users to have to depend on dongles.
This play would kill USB Type A connectors in favor of USB Type C, in addition to eliminating backward compatibility with older devices that we have at home. One solution manufacturers can implement instead would be to include two USB controllers to offer full ports or backward compatibility, although this would probably only be done on desktops, where space is at a premium for laptops and only one would likely be included. . Another option would be to rely on external adapters to handle this conversion.
This can cause major problems with current devices that use only USB 2.0, such as many keyboards or mice released in 2020. Currently, computer motherboards have up to three different connectors depending on the USB standard that each connector uses.
