I don't have Jolla's roadmaps and I don't have any foresight on their plans. Unless Jolla confirms that they will support that feature in the future, I use word "might". I expect them to implement it.

I'm getting that WPA EAP is very important for you. If you like to get your feet wet, you can download Sailfish SDK and implement your own application for configuring and enabling that feature, and then publishing it to others to try and use. At least you could get a good adventure.
