Really need an option to delete "guest" account?

Hello,

I was informed that apps support account creation must also include an option to initiate account deletion, including "guest" accounts.

However, I'm not sure that I really need the option for guest accounts because the guest account is automatically deleted when the user uninstall my app.

Would you please let me know that I still need the option for the guests?
