Indeed, as an heretic, one of the first things I did with Jehanne was
to move the console filesystem out of kernel.
Then I moved several syscalls into userspace. Or turned them to files
or to operation on existing files.
More syscall/kernel services will move to user space as I'll have time
to hack it again.

You know... heretics ruin everything!

I'm not going to turn Jehanne to a microkernel, but I'm looking for
the simplest possible set of kernel abstractions that can support a
distributed operating system able to replace the mainstream Web+OS
mess.
You know... heretics are crazy, too!
