This tool has huge potential for WordPress users who wants to manage multiple sites and servers. Focus solely on WP and Docker conteinarization is great choice but the main problem is team behind FlyWP. Based on many discussions on FB regarding security issues and crashing sites after updates I think this piece is too much for the team and if they don't hire expert for servers to lead the development I think problems will persist. This can be the best tool out there but everything is about the right people.
