It worked just fine in B/X and BECMI, and those are D&D too. Even 1e, 2e and 3e did better with it then 4/5e. "D&D" may or may not only refer to the official game, but it certainly refers to more than just the current official edition. The point is, 4e and 5e straight-up removed game options that used to be present, resulting in an experience that is, to me, less rich.
Did it? Because I don't remember anything other than "you get followers". Okay ... so you got followers. So what? What do I do with them?
I don't care if they removed features that didn't really work and we never used anyway. Let it go the way of the Dodo bird like weapon speed and doing different damage based on the size of the target. Good riddance.
Meanwhile not including them frees up space for 3PP to design something that you actually do like. Seems like you're ultimately getting what you want, I don't understand the complaint.
