What to do with the book.multilingual field?

Question

The code here

mdBook/src/config.rs

Line 424 in 4f698f8

pub multilingual: bool,

expects a field called multilingual in the [book] section of book.toml.

The mdbook init command even ads it to the book.toml file.

However, this field does not seem to be used anywhere in the code and it is not mentioned in the documentation either.

Shall we remove it from the code and start warning about its presence?

Yea, I have no idea what that field is for, and it doesn't look like it was ever used. I'd be fine removing it.

Reopening since I overlooked that this would be a breaking API change.
