Well, unsurprisingly (given that I filed the bug), I have a different
perspective.

I think deleting collections may be quite a bit more common than
deleting email folders.  Here's my use case:

I want to buy tickets to a basketball game to attend with my brother.  I
don't care a bit about the Warriors schedule for most of the year (since
Michael Jordan stopped playing I can't bring myself to pay attention to
the NBA like my brother wants me to), but I figure the most convenient
way to browse the Warriors schedule is to download their season as
iCalendar, which creates a "Warriors schedule" collection.

I overlay my calendar with the schedule, find the games I want to see
with my brother, add them to my personal calendar collection, then
delete the whole Warriors schedule collection.

In this case, I very much want to keep the games I added to my personal
collection around, that was the whole point!

Sincerely,
Jeffrey
