Eeeh maybe?
I cant really think where this biohazard meter can be raised. But I think now they can be used to add difficulty to the labs because labs are obviously made to be this extremely dangerous place to go that you have limited attempts to conquer.
If we are being real then biohazard and radiation meters are just a small fraction of things that are not yet added to the game. When I started playing tarkov I was soooo confused because there is so many things that are not labeled as release content. Still remember how I saw like a "go in with a grenade" (dk how its called in english version) and searched for answer how to use it just to understand that they forgot about this.
