You can minimize that to some degree (Valorant does this), but due to movement prediction/network latency you do have to overshare a little bit.

I imagine that most game devs just look at the incredible amount of work this takes to implement and complexity it adds, and decide to not bother. Valorant can do it because the game itself is low complexity, the developer has deep pockets, and also the added competitive integrity is valuable.
