Is TornadoFX stable/well-established to be used for production?

Dear community,

I am looking for Kotlin GUI frameworks to build my startup. I would like to make a good first choice to avoid major rework in the future. I have seen TornadoFX to be suggested in this subreddit. I would like to ask if TornadoFX is mature enough and trustworthy (in terms of relaying on it for future updates) to build a software for production? Do you recommend it for such applications? If not, is there a better option out there?

Thanks!
