That's what ZSH has turned into. Every new user installs OMZ because that's what the Internet tells them to do. Then their shell config turns into a huge mess.
So half the users are using OMZ with a bloated slow config and the other half are reinventing new config managers every year because of how terrible OMZ has become. And constantly churning through them as they keep getting abandoned.
I've been happily using zsh4humans for years but will need to find a replacement at some point as it's now going unmaintained too.
Learn your tools first, not bloated frameworks. There's a gulf of difference between vanilla zsh and this:
>Community-driven (with 2,400+ contributors) framework for managing your zsh configuration
>Includes 300+ optional plugins (rails, git, macOS, hub, docker, homebrew, node, php, python, etc)
>140+ themes to spice up your morning, and an auto-update tool that makes it easy to keep up with the latest updates from the community
