The reason they don;t is because of console, that's it.
The you have to choose etc it's all bs, even with many other skill slots you still wouldn't be able to do everything.
In any case it's not like you have any real choice if you wanna be the best you can.
Some skillsets are just better than others.

The ability in this slot doesn't change with weapon swapping. It can be activeley used and any passives tied to it are granted all the time. Pretty much every class has a skill like this and if they don't, there is always a universal skill available like Camo Hunter or Inner Light. These skills often times take up slots just to passively gain their bonuses.
Another option is to to characterize certain abilities as "Utility", these skills are the only 1's that can be slotted in this position, but if the player chooses to, they can still slot them anywhere on their normal bars. Warframe has something like this for mods that give extra sprtint speed, loot radar, etc. Their game originally didn't have those slots and were implemented later, but it made these underused abilities much more interested to choose from and build diversity went up. It's never too late.
To the whole console limitation arguement, controller utlimates are tied to 2 button presses with left and right bumper. The same can be done with a new utility slot, buttons like the emote button are also kind of useless, you can change it to be tied to the consumable wheel. It's a limitation only if you lack imagination. Tons of games have many more button presses then eso. This is just 1 new option.
The final option is to just make the slot passive, but I think that's very boring, that being said, many builds are double barring abilities like Flame Lash, Inner Light, Bound Aegis, Camo Hunter, Psijic Order, etc.
Now if you consider the current state of the game, then yes maybe a new slot wouldn't be the best, everyone would slot Inner Light and every mag build would have those bonuses + stealth detection. There is numerous ways to make it work, simply by changing the amount of passive magicka it gives to make other options more viable or a situation where CP or the overall dps potential of every build wasn't quite as high.
We've already seen this done in this patch with the nerf to dots. Things change and need to be evaluated against everything in the game instead of in a vaccum or the current context of the game. CP is set to have some changes down the pipeline, so if damage being too high is another argument, I think that's something that can easily be balanced at the time of introducing a mechanic such as this. The biggest benifit is to further build diversity, yet still keeping the restrictions in place that make choosing abilties with the limited bar space meaningful.
