Of course. Never thought you meant anything else.

Which is what I've been trying to say all this time. If the scheduler can't
handle dynamic code, then it's not really a general system.

I've given you several examples of very mundane and common uses of dynamic
control flow that wouldn't be possible for this reason, so I believe I've
made my point pretty clear on why this is unlikely to be acceptable for me
at least (especially since the benefits are requiring these restrictions are
highly dubious, IMO).
