the wake is deliberate input injection by privileged code, which is exactly the kind of thing this document exists to state precisely rather than leave to be discovered in the diff: why it must run in the root service (uinput is root-only and the compositor holds drm master), what it can reach (only an already-authorized _drm connection triggers it), how narrow the trigger is (a connected-but-undriven connector, with a self-refuting per-connector memory for the hopeless ones), the rate bound (one wake per 20s process-wide, single winner), the device lifetime (created and destroyed around the emit), and that a host without /dev/uinput loses nothing it had (such a session was already view-only).
