I am!
Currently there is a docker app called "OpenFAN Unraid Service" which is documented here and source code is on GitHub.
Feel free to contribute.
This is a relatively "hacked up" solution but it works exactly what you asked for (I use it every day and know multiple people who said it does the job for them).
But I am also working on a more functional version that will support plugins, drivers and eventually have a nice GUI. Obviously this will take some time...
p.s. Keep in mind that this is not a stand-alone app. You will also need to run the original OpenFAN Unraid App (link here).
