Plain text is internally ropes-something, indented with meters of vimscript, colored with a syntax model that is okay to change, hard to create from scratch, etc. it’s all hidden from a regular user who uses a subset of all features.

But if you ignore the non-ms movement, shortcuts and advanced transforms, it is still a text editor that everyone may use. You can’t put your text (text, not a current mode!) into a state that looks okay but requires a vim guru to continue or start over because something is broken in the model. That’s different from git issues where working copy looks okay, but the branch and merge are broken in subtle ways.

>Plain text is just a lot simpler than a VCS repository.

Than a Git repository, not a VCS one. Not saying that VCS = plain text, but much simpler models exist for merging teh codes.
