This is probably because three of them are also Cutie Mark Crusaders based. We had Rainbow Dash and CMCs in Flight to the Finish, Applejack and CMCs in Somepony to Watch Over Me, and Rarity and CMCs in this episode.

But now that they're all used up, I'm pretty positive there certainly won't be another episode like this in any further CMC based episodes.

And one last thing -- had Rarity and Spike NOT appeared in Rock Solid Friendship, Pinkie Pie would've had an episode where she would be the only one of the Mane Six in it, followed by Rarity two episodes later.
