The simple-normality conjecture for the Fibonacci concatenation

The Fibonacci concatenation is the infinite sequence obtained by concatenating the Fibonacci numbers. A sequence is simply normal in base $\beta$ if each digit occurs with limiting frequency $1/\beta$.

Simple-normality conjecture. The Fibonacci concatenation is simply normal in every base.

The source proposes this as the route to proving absolute normality: simple normality in every base implies simple normality in every power of every base, after which the cited lemma would yield normality in every base. The conjecture remains open.
