zsh doesn't require any 'plugins' for its tab-completion, everything you need is distributed with the shell. A lot of people who use zsh just don't understand how it works and think that OMZ/Prezto/whatever are doing something special for them that they couldn't achieve themselves with one line in their .zshrc (or that may even be enabled by default in their OS's global zshrc, as is the case on Ubuntu for example)

Yeah, I went that route before settling into Oh-My-Zsh. The thing is, those single lines add up quick leading to increased mental overhead and time investment.

It's never been about 'understanding' zsh or not, it's always been about making it comfortable to use, quickly, on any given system I might use.

Sometimes a nice set of defaults is more productive than a custom solution.

I agree that zsh's default configuration sucks (and the new-user wizard is overwhelming). I would like the project to provide a more opinionated set of defaults to OS vendors; i think we are probably just nervous about breaking 30 years' worth of expectations, and so far nobody has really pushed for it.

But i do think the misunderstanding i mentioned is very common, as illustrated by the fact that the GP seems to think that OMZ itself provides zsh's completion functionality. It's also a frequent point of confusion with people seeking assistance on zsh's IRC channel.
