The Governing Body really doesn't need the "Faithful and Discreet Slave" parable or a literal 144,000. I foresee them clarifying/discarding both of these soon.
Instead of using the Faithful Slave parable, they'll simply use the First-Century Jerusalem "Governing Body" of Peter, James, Apostles, and Elders as their example, justifying their authority.
After all, all other churches have authority structures without needing special parables justifying their existence.
I can see them shifting and saying the 144,000 may be literal or may be symbolic-- just follow your spirit/heart on whether to partake.
This would explain and justify why there are so many younger Anointed or a younger Governing Body.
It also might draw a larger number of people to have Bible Studies if they bring back the Heavenly Hope to a large number of new believers.
