I just replied to your followup elsewhere in this thread, where you
indicated that no markers would be needed.

Are you saying that the marker will be unnecessary in later versions?
(If not, why not just say "A marker will be used" without reference to a
release number.)

My questions stand for later releases.

Again, I suggest that speculation from others is not helpful.
