Title.
This is cvar, and it's used by the engine in some functions. Similarly in rehlds:
https://github.com/dreamstalker/rehlds/blob/master/rehlds/engine/host.cpp#L841
it is useful then? as a cvar for a regular player usage seems useless.
I think we should have a more compelling reason to remove already existing things. Perhaps cvar does not bring enough benefit, but it is still used somewhere.
Then we should just hide it somewhere as it has no effect on actual game but code.
A lot of cvars only affect the engine, that doesn't mean they should be hidden.
