I like the user facing design, but how am I supposed to use it internally?

Say I want to read a value preferably from the worktree I'd do a

     * the user is supposed to do that?
     */
    repository_format_worktree_config = 1;
    git_config_get_{string,bool,int} (... as usual ...)

and if I want to read the value globally I would set the variable to 0
and read? (I would need to restore it, so I'll have a temporary variable
to keep the original value of repository_format_worktree_config)

I would understand if you need an api to write to worktree config or
the shared one. But choosing to _read_ from a specific source sounds
wrong. The common rule should apply everywhere: read from worktree
first, if not found, read again from shared config. Why do you need
this?
