Well, they got away with that in 5.0 because... (5.3 spoilers also under cut)
...Shadowbringers' plot ultimately works the same even if you haven't played CT - at least if you don't look at it too closely - because of the time travel aspect. The script adjusts to the scenario that you haven't yet been to the tower or met G'raha Tia but you (other-timeline you) will/would have at some point in the future shortly before the Calamity hit. The events of CT definitely happened in the Exarch's past, whether or not you have yet experienced them in the present. Thus the script can be altered to fit either scenario, even though the canon version has CT happening first.
It can't work the same way in 5.3 because the events here and now require CT to be completed first. You can't plan to open up the present-day Source's tower and awaken G'raha if he's not in there yet.
