A few months ago there was a shortage for power delivery controller for USB4 and TB4. This article gives details about the issue. In short because of the shortage many laptop makes had to use older power delivery controllers that arn’t compliant with USB4 but offer the same end user experience. Intel gave laptop makers the permission to temporaly use the older controllers with TB4. Intel also recommends to market affected laptops to only mention that the TB4 port is “compatible” with USB4 or to not mention USB4 at all. @nrp is the framework laptop affected by this issue?
Update: It looks like framework uses parts that fully support USB4. My fear that it might only support TB4 but not USB4 completly was invalid then ^^
