Is Epoc Flex supported?

First, thank you all for the huge effort done towards this project.

I wanted to know if the current code will support Epoc Flex 1.0

If so, do I need to use keymodel 4 (insight) to get it working?

I've been reading old discussions from the past years about this topic, but I'm not sure what part of the discussion was already incorporated to the current code.
