All commercial types advises to increase the approcah speed by a certain factor depending on headwind (e.g 1/3 f HW component).

"Mistakenly" it is considered a safety factor to overcome a sudden decrease in HW, as protecting the normal app speed (KIAS).

No, this is not correct, it may be only a side effect.

The main reason: As increasing the App speed depending on HW, the cockpit view (cut off angle) remains same for a fixed path approach. For example in an ILs approach with 3 degrees, if the same app speed is maintained regardless of a strong headwind, body attitude (but not AOA) would be higer than normal, as reducing the cockpit view through windshield.
