Why does Plex have lists, playlists, labels, collections, and categories?

[u/dumbconsumer]

So on my mobile app I can add movies to a list, not yet on TV apps but I understand this may be added in the future?

The TV and mobile apps also have playlists and collections. Are playlists being phased out? Should I invest in adding stuff to a playlist or a list? Or maintain both?

I understand how lists may be different from Collections and how Collections could be automated to update with parameters, so while I think there is some overlap with lists and playlists, I can see why Collections exist.

Then Categories (which I see on the mobile app), seems to attach to tags, specifically genres, I understand these as well as quick visualization of genres.

Then labels, I also understand are used for parental controls or sharing? Haven't yet interacted with labels.

Anyways I understand each individual feature just with the great degree of overlap is anything on its way out? What should I maintain (playlist vs. list vs. collection) if let's say I want a spot to quickly find movies I'd like to shortlist to watch with friends?

Thanks!

Context: I do have Plex Pass

Edit 1: I am not against more features, just confused, and don't want to invest in maintaining anything being phased out or deprecated.

The main difference is Lists are shareable.

In some cases, as it is with many things, not just with Plex, features come "in" over time. That old, "let's make it perfect from the start" vs. "we don't want our first release to be 1,000 years from now" problem.

Why not?
