These are some characteristics of Google Calendar considerably unique from other calendaring systems.

---

Not only primary calendar, we can schedule meeting through other calendars too.

Meeting owner is also a guest in the list.  When meeting owner changes response to "No", it is not meeting cancellation.  To cancel a meeting event, this procedure is suggested:

1. Enter the meeting item (edit event details).
2. At Guests list, choose "Email guests" to inform cancellation.
3. Next, click [Delete] button at the top line of calendar form

In case we also show other people's calendars and have schedules in common (either via meeting responding or copy-to-my-calendar), so far there's no solution to avoid redundant displaying.  At least there is a reason: we can edit our own instances.

The note next to response in a meeting, when input, is shown under our name in Guests list.  It is not for corresponding.

Meeting notification to inbox is just an email copy in addition to calendar item itself, with ability to respond and link to the event item.

• It helps for people who don't open calendar regularly.
• It can be used for replying as email.
• It can be deleted with no effect to the event item in calendar.

We can reply "No" to a meeting but leave it stay in calendar: i.e., different from "Remove".  Turn setting "Show events you have declined" on.
