Redox is drama-free because Redox has very few developers working on it. In the last 12 months, Redox had 7 contributors that touched more than 100 lines of code.
Hard to have too much drama if you have a handful of developers that do code changes, and no users to complain about any of your decisions.
I am sure most people involved with the Linux rust effort are also not problematic; these would be very welcome there.
OTOH, please don't let Redox be taken over by problematic people.
