The term is 'security by obscurity' and it doesn't work. Because it's only a few bits of information and once documented it is a matter of time before the data is out there.
In this case: the data is the same for large swaths of the former USSR so it isn't strange at all that an enemy actor has access to that information. Poland could do the exact same thing to Russia. But I hope they have better ethics.
