We certainly have plans to add WPA3 support. Given the demand, it'll probably be sooner than later when we add it - but I don't have a timeline as of today when it will be implemented.
We should have a publicly available roadmap. It can be complicated, because a lot of times our roadmap changes and shifts. Having a public roadmap makes it more set in stone and immutable to future changes, but there is certainly merit to the idea and I'll give it some thought.
