Problems enabling rule `wrapping-the-expression-body-of-a-function` via `.editorconfig`

Seems that I need to set ktlint_standard_function-signature = enabled instead, although this rule is listed as an experimental rule?

This is not clear to me reading the docs:

This setting only takes effect when rule function-signature is enabled.

Maybe its worth adding an example how to enable this?

There was already a kind of warning on top of the Experimental Rules documentation:

Would it be more clear if I change the last line this message as follows?

Or, when a specific experimental rule is provided in rule set with id rule-set-id, it can be enabled via .editorconfig property ktlint_<rule-set-id>_<rule-id>.

I will change all rule ids on the experimental and standard rules pages to the fully qualified rule id.

This is not clear to me reading the docs:

This setting only takes effect when rule function-signature is enabled.

This means that the experimental rule function-signature needs to be enabled. Either enable all experimental rules or enable this specific rule.

I think my first confusion is mostly because it was not clear if the rule ktlint_function_signature_body_expression_wrapping is a standard rule or an experimental rule, since its listed under KtLint configuration. I guess its neither of both.
However, I did not know how to translate this advice into a .editorconfig:

This setting only takes effect when rule function-signature is enabled.

Maybe just add the following:

This setting only takes effect when rule function-signature is enabled (e.g. via ktlint_standard_function-signature = enabled in your .editorconfig).

The second confusion was because of this sentence in the important box:

Or, when a specific experimental rule is enabled via .editorconfig property ktlint_<rule-set-id>_<rule-id>.

I am missing some information about what the rule-set-id actual is. I though function-signature is the rule-id and since this is an experimental rule experimental would be the rule-set-id. But its ktlint_standard_function-signature instead.

Is that because the first sentence in the box states?

Experimental rules in ktlint are part of the standard ruleset.

I think some pointer on what a rule-set-id actually is would help to make it easier to understand the required config keys.
