Rj__M , we did consider reducing the options to just two ("Yes, in person" and "Yes, virtually"), but ended up preferring to give our users the flexibility to choose if they want or not to disclose their location/attendance mode while they are responding to an invite.
Why? Because there cases where users cannot or do not want to share an attendance mode. Just imagine for a sec that you want to respond immediately and already book that time as busy, but you are not sure yet if you will indeed be able to attend in person. Therefore, we will initially launch this feature with all three options and monitor how much usage each one gets. With post-launch usage data and user feedback, we will be better fit to assess what is the best user experience for our users: all three options (Yes, in person | Yes, virtually | Yes) or just two options (Yes, in person | Yes, virtually).
