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
endand 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.

Remove redundant safe navigation operator (`&.`) in `result.to_s.strip.present?` check, as `to_s` handles `nil` gracefully by converting it to an empty string. This makes the code cleaner and more idiomatic without altering behavior. Ref: https://ruby-doc.org/core-3.1.0/Object.html#method-i-to_s
