Not really. Polling at 1ms intervals is sufficient for rotary encoders.If you run rotary encoders to a port expander, I would propose to route the INT output to the MCU to have faster access instead of polling the external port.
Or you could use the INT pin to handle any/all inputs. No need to handle rotary encoders specially.
