My closed-souce WIP is a strategy game I started back in 2013. (I’ll post a screenshot someday.) It uses Minie, but as far as I know it won’t need soft-body physics.
I’m working on soft-body physics because I think it’s cool and I hate to see Dokthar’s work languishing in a private fork, untouched since 2016. I hope people here will dream up uses for it and those uses will motivate them to use Minie.
As long as JME supports both jme3-bullet and jme3-jbullet (and tries to maintain compatibility between them) I doubt soft-body physics will ever be part of default JME.
