Define the display of the scoreboard to players via the selectors

I am a creator of a full vanilla/data-pack minigame server but I have a constraint, we can only set the scoreboard display to players only with teams. The suggestion that I propose you in the next versions, we can define the display of the scoreboard to players via the selectors (@a, @p, @e, @s, @r...). We can make for example "/scoreboard objectives setdisplay sidebar test @a[scores={test=1}]" to display only to the player with a score of 1 in test.
