They must have had a checklist of things that _needed_ to be included. I imagine it must have been an absolute conundrum to figure out how to include all of it in a way that makes some amount of sense.
Chrysalis was the longest-standing villain, so they have to do _something_ with her. _If_ she can be redeemed (and even the people who want her redeemed have to admit that's a big if), it would be a longer journey than the show has time for. But she really doesn't have the personal connection to Twilight.
Waiting in the wings are two other villains that have been major threats in the past. One of whom has defeated Discord. Speaking of.
Discord was MIA for the last three big adventures, so they can't not include him in the grand finale. Which means they have to contrive some way for him to lose his powers.
Let's ignore the potential structuring issues of an alternate "The Ending of The End" for now. Whether it's Grogar or Discord, the first step of redeeming these characters happened because they were sent on the mission to retrieve the bell.
