Cards exiled with Brainstealer Dragon should go to unique exile zone

[PurpleCrowbar]

Cards exiled with [[Brainstealer Dragon]] can be cast by its controller for as long as the cards remain exiled. Currently, the exiled cards go to the generic exile zone. Instead, they should go to a specific "Brainstealer Dragon" exile zone so as to make it possible for players to tell which cards are available to themselves / their opponents.

Brainstealer Dragon - (Gatherer) (Scryfall) (EDHREC)

{5}{B}{B} Creature — Dragon Horror 6/6 Flying At the beginning of your end step, exile the top card of each opponent's library. You may play those cards for as long as they remain exiled. If you cast a spell this way, you may spend mana as though it were mana of any color to cast it. Whenever a nonland permanent an opponent owns enters the battlefield under your control, they lose life equal to its mana value.

This is a good a place as any to ask a question.

What was the logic of a shared exile zone? (I am used to seeing separate exile zones for each player, so the shared one initially confused me.)

In the rules, there is only a single exile zone. Grouping by owner or by usage with the exile zones is just something that is done for convenience. And we lack some generalized way to achieve that, so each card is on its own on what exile zone to use.
