Does CodeMirror 6 support (plain)text language mode?

…and how to use it?
I cannot @codemirror/lang-text or something similar anywhere…

There is nothing at https://github.com/codemirror/language-data/ project, or at CodeMirror’s documentation.

What do you expect from this mode? Just not loading a language extension will let you edit without highlighting or language-related features.

Sorry, newbie question, I thought you always have to set some language.
Thanks.
