I called apple support. I'm assuming they were first level support. They were clueless on current or previous snooze functionality. I do see that the missing calendar snooze functionality exists in Reminders. I found an apple KB article that says you can create a reminder from a calendar event by double-clicking on the event, then Ctrl-clicking the title of the event and selecting the Share option. From there you can choose to share with the Reminders app. Unfortunately, the share function only creates a one-off reminder, that you must manually configure. If the calendar event is rescheduled, nothing happens to the reminder, so it's pretty much a waste for me. I have meetings rescheduled all the time. The support person was clueless about the share functionality, as well. I wanted them to tell me if the calender event and reminder were linked, but they didn't even know you could create a reminder from an event. Instead, they wanted me to test it out, which I already had done. I just wanted them to confirm my findings, as the "experts." So, another mac app I will have to abandon. I use Spark Mail instead of Mac Mail. And now I'll have to use Outlook from my Microsoft 365 account just for my calendars (prefer Spark over Outlook for mail). Disappointing, but not surprising, because Apple must believe they know what's best for everyone when they do s**t like this.
