Are you aware that the speed of light is limited?

That is the main problem here. If you only give players the data they can see (zero trust) - then they will walk around a corner and just see a black screen, because the information is not there yet (server needs to calculate and send back info in time).

My approach would be rather better moderation tools.

Meaning .. community run servers, who will just kick and ban cheaters in time.

One can see that clearly in battlefield for example which has (sort of) both.

The public servers are often not enjoyable, if one does not like headshots across the map. The community run are clean.
