Why can't we see the enemy summoner spell cooldowns with tab?

Roughly 2 years ago, Riot made a post about clarity when they were adding the first jungle timers to SR. They stated:

> Boiling down what we talked about in our design values, League of Legends provides three basic paths to mastery: personal expertise, teamwork, and adaptability – our focus will be on the first. Personal expertise is a complex soup of skills but we can generally agree that elements like mechanical mastery, situational awareness, and game knowledge are vital ingredients.

>Most of these are universal to the League of Legends experience and are agnostic to the map, mode, or champion you play – though a few of them can be overloaded based on your preferences. Regardless, we’ve also declared that a few things aren’t part of the experience, like hardcore multi-unit micromanagement, rote memorization of patterns, or bookkeeping.

>Jungle timers fall into that last case, and serve as an example of important information being presented in an impractical manner.

So back to the question at hand; Why can't we see enemy summoner spell cooldowns when hitting tab like we can see ally summoner spell cooldowns the same way? If they decided to change the jungle because of bookkeeping, why can't they do the same here? Pro players will chat (with timers) when the enemies flash so they can keep track of the cooldown themselves. But, as Riot said, this is a form a bookkeeping and therefore should be fixed since players should not be required to memorize the timers as its not part of the experience. There is already a way to see if the enemy has Insight or if they have which both reduce the cooldown of summoner spells. This is extra bookkeeping that, again, is not part of the experience and should be changed.

Now obviously you would need a vision aspect of them using the summoner for it to record the cooldown (This would prevent you from knowing the enemy ___ used flash in fountain and therefore does not have flash).
