Chapter without intro file

[fortierq]

Context

I would like to have a chapter that is not clickable and does not contain an "intro" file.

For now, I have to specify a file like this:

format: jb-book
root: intro
parts:
  - caption: Bases de données
    chapters:
    - file: 1_sql/cours/cours.md # I don't want to use a file here
      sections:
        - file: 1_sql/cours/sql_select.md
        - file: 1_sql/cours/sql_join.md
        - file: 1_sql/cours/sql_groupby.md
        - file: 1_sql/cours/sql_nested.md
        - file: 1_sql/cours/sql_entity.md
        - file: 1_sql/resume/sql_resume.md

Proposal

Is it possible yet ? Do you think it would be useful to implement it (I could try) ?
