Please add the possibility to install Kodi on Roku TV and devices.
How do you want us to switch to Roku from Amazon Fire TV when there is less flexibility and less application on it?
I am not sure it is up to Roku to develop a Kodi client.
However, I share your frustration and disappointment that it is not available. I had to settle with using minidlna and the roku media player channel. It is primitive.
