So originally we planned to keep the "hero-ordinary" disparity in Modern20.
You probably know that because there's some artifacts of those rules still in the book.
The biggest one of these is the Sidekick feat, which no longer does anything, since all followers are now the same as everyone else.
This is the feat that will replace it in the next Modern20 update.
You fine folks get it first because you're better than everyone else.
You have one or more devoted followers.
Prerequisite: Reputation 3+
Effect: You gain +6 RP that can only be spent on followers.
