Number of items not appearing next to items

This is a genuine & non-snarky question -

My use case for having item count next to items is this: When doing vault item management, visible item count for all vaults provides a small confirmation that I've made my intended changes.

(I do understand the arguments against putting item count next to items: visual clutter; keeping those counts updated.)

But I don't understand the "user story" for putting item count at the bottom of the list. What purpose does that serve? Who is that useful to?

It's dreadfully inconvenient when doing vault item management. Changes aren't visible immediately, only one count is visible at a time, and multiple clicks are required. It isn't possible to use the keyboard Page Down or End to scroll to the count - it's a weird bit of UI/UX, and it remains off-screen. So the mouse must be used.
