Sorry, I’m a bit lost regarding your comment. The discussion was about code safety in Linux in the context of potentially introducing Rust. I don’t really see the link with microkernels in the context of safety oriented RTOS. I think you are reacting to my comment about microkernels performance in the 90s which I maintain.

Neither QNX nor ThreadX are intended to be general purpose kernel. I haven’t looked into it for a long time but QNX performances used to not be very good. It’s small. It can boot fast. It gives you guaranty regarding time of return. Everything you want from a RTOS in a safety critical environment. It’s not very fast however which is why it never tried to move towards the general market.
