iOS 18 calendar

I just upgraded to iOS 18.01 last night. 

I use my calendar in List view.  Some of the event entries now have a
little calendar icon next to them whicle others have the usual vertical
colored line.  It seems this is to denote all-day entries.  Apparently
there's no way to remove it despite it taking up valuable space and
being completely unnecessary.  At least they gave us a way to disable
Reminders in Calendar, so why can't we have a way to disable this
stupid calendar icon within the Calendar app?

I left a comment at Apple's website, but they are much like Google when
it comes to listening to customers.
