It's detrimental in the sense that it gives you a false sense of security (literally.) We have no idea how many people/states broke TETRA before one made it public. And there is no feedback mechanism to get to know it either. If the algorithm is out in the public, public research funding provides an incentive to publish findings, creating that missing feedback loop.
