Everything that can be done with NIP-36 & NIP-56 can be done with NIP-68/69. It makes no sense to have competing methods of doing something as basic as reporting illegal content.
They won’t be the first NIPs they have been deprecated. NIP-08 is deprecated already - and that was also a really basic function where it was counterproductive to have multiple ways of doing it (mentions).
Only NIP-01 is mandatory. No one is forcing any relay to implement NIP-69.
