Calendar apps are so complicated and tightly integrated with other productivity apps now I'm not sure the benefit of simplicity here outweighs the cost of losing that.
My Google cal emails me notifications, works with desktop calendar apps, integrates with Maps, etc. It autofills addresses, adjusts for time zones, syncs across my 4000 devices, allows me to edits dates via text input or GUI/drag 'n drop, etc. (Not shilling, Apple cal is probably similar.)
Even my todo list went from org mode to Google Tasks because of the integrations with Android, Google Calendar, etc.
