Yes, the generic layer should expose throttling. But before it does so, it needs to learn that T-states have very different implications from P-states.
Indeed it is a bug in the current architecture that P-states are exposed by cpufreq on some systems, and T-states are exposed on other systems, and they are treated like they are the same.
It is also bug that T-states are exposed on some systems, while ACPI is simultaneously assuming exclusive access to them for thermal throttling.
