Docker - CUPS sensor

Hi,
Do we/you know when cups sensor support will be added to the base docker image for RPI2/3?

For now I’ve added below in for my dockerbuild file:

FROM homeassistant/raspberrypi2-homeassistant
RUN apk add cups-dev python3-dev linux-headers musl-dev gcc --no-cache
RUN pip3 install pycups
