unless I'm missing something and in some circumstances to_s can be nil (maybe override to_s, but that is a user problem)

It may happen in AR when you do something like

class MyModel < ApplicationRecord
  def to_s
    name
  end
end

and name is nil.

But this should not be expected and is hiding a problem

This should be implemented with delegate :to_s, to: :name

Feel free to reject this change

I made this update in #6342 but I don't recall why I used the safe navigation operator. Likely just out of caution without really knowing that nil.to_s will return an empty string so it is redundant as you say. This looks good to me and makes sense to change. Thank you.
