But it is the default way.

As it is not required I think stating it is going to create confusion.
Users may not know whether rng-tools is optional or necessary for
feeding kernel entropy pool.

Hmm, the tool still exists and can still be used to feed /dev/random.

Feeding /dev/random directly from the kernel is just one way of
using hwrng.

So rather than removing it perhaps you can modify it to state that
the kernel can now feed /dev/random as an option.
