Where is this requirement? Section 5.6 of the HID spec says:

Note Only Input reports are sent via the Interrupt In pipe.
Feature and Output reports must be initiated by the host via
the Control pipe or an optional Interrupt Out pipe.

So if there is an Interrupt-OUT endpoint, it should be valid to use it
for a Feature report.
