self.method_missing on require respond_to_missing as instance method instead of class method

[Rataah]

Hi,

For some reasons, I defined the method_missing as a class method.
The corresponding cop rejects my code because respond_to_missing? is missing.
I assume this method should be a class method too but this doesn't work. The cop accepts only if I declare an instance method.

Here is an example:

# Rubocop method_missing issue
# this should be OK
class GoodExample
  def self.some_method
  end

  def self.method_missing(method, *args)
    super
  end

  def self.respond_to_missing?
    true
  end
end

# Rubocop method_missing issue
# this works but not as we expect
class BadExample
  def self.some_method
  end

  def self.method_missing(method, *args)
    super
  end

  def respond_to_missing?
    true
  end
end
