Is it so that such notes cannot be used?.

Knowledge is power.
Similarly in between for some time the shopkeepers stopped taking the notes on which in the white portion something is written. This was there for only a few days. But now all are accepting these notes. In between, there was a confusion about this but after the clarification from RBI, there is no problem.
It is not good to write in the notes unnecessarily. The notes will get spoiled quickly. I think there is no rule in force saying that nothing should be written in the currency notes on its white portion. As of now, these notes are valid and they should accept these notes. If there is any difficulty we can take them to any bank and get them exchanges there.
Thoughts exchanged is knowledge gained.
