The roadmap as presented by Apple at WWDC 2019 was that after an userspace replacement for a kernel subsystem gets presented, there is one year deprecation until it gets removed from the kernel on the following OS release.
So there is one year to try out what might still be missing and give respective feedback.
The long term roadmap is that macOS will eventually be much more microkernel like.
