I've been riding a 1950's IGH/Derail hybrid set-up that uses a SA/AW hub with a 3 cog Cyclo adapter for decades.
Although it has both the advantages
and disadvantages of both the IGH and a rear derail it provides a useful gear range of 41-106 GI with the ability to shift at a dead stop. Heavy, complicated, fussy and requiring advanced math to determine which lever moves which way to shift into the "next" gear it has proven ideal for my town bike requirements.
Sometimes the old tech is still most appropriate or even "just right".
