It is slightly relevant. If you have a substantial amount of trim set
for a control surface, the distance remaining to the limits of its
travel are substantially modified, and you may forget about the trim
and mistakenly believe that you have more remaining control authority
than actually exists.

You are presenting yet another absurd scenario that has no relation to the
reality of flying. Nobody flying a real plane will "forget" about trim set
near the limits of it's travel, because the control forces are a constant
reminder.
