Eh, egg on my face, then. Must be a PC thing, cuz on PS4, I only ever see one page of 25 slots for Key Items. I've never actually filled the entire page, but with the right quests open I know I easily could have. It could be that a second page becomes selectable once the first page is full, but by default the second page isn't viewable on PS4, as far as I know.

If there really is no limit to the number of Key Item pages, then it probably wouldn't be terrible to implement armor storage using Key Items - though it does have the potential of introducing a lot of clutter to the Key Item inventory...
