A clear yes: this is part of the long-term roadmap we are currently
preparing, just stay tuned. In fact, Philippe expressed this goal
already in earlier announcements.

Having native (patch-less) real-time will indeed be an interesting
option for the future, besides co-scheduling.

There once existed a combo patch (that I don't find ATM) of an ancient
-rt version + old Adeos, a combination that will more or less
automatically come again when PREEMPT_RT is mainline. Porting the
nucleus over PREEMPT_RT so that the skins can run "natively" is another
task yet to begin. Anyway, we are already including this perspective in
current design decisions when subsystems are revised or enhanced.
