Atmospheric drag is too difficult to overcome to achieve the projected range. I would guess the cannon functions similar to an ICBM. Hurling a projectile into low earth orbit where it can travel long distances without expending too much energy. Re-entering the atmosphere to impact its target.
Part of the problem is the F-35 lacking the range to compete with china and russia's fighters. While a 1000 mile range is impressive. The accuracy could not compete with the laser precision of guided munitions launched by aircraft. Significant disadvantages over the long term.
