I do not know if I would at all. As I said, it is an informal
convention. It skirts a number of corner cases, and as soon as you try
to build a sound implementation, you are forced to address those,
which breeds incompatible dialects.

(As a few examples, on the first sight, it looks as if the dotted path
is a dot-separated concatenation of unquoted object keys going from
the root object. What do you do if one of the keys contains a dot? a
space? What if one of the keys being traversed is an empty string?
What if you need to traverse an array?)

I just expect people to be able to read
‘rust-analyzer.assist.emitMustUse (default: false)’ in documentation
and write

    {
      "rust-analyzer": {
        "assist": {
          "emitMustUse": true
        }
      }
    }

in a JSON config or

    rust-analyzer:
      assist:
        emitMustUse: true

in YAML.
