It simply doesn't work, e.g. you could not statically disable logging in 
phobos without recompiling phobos.

cat > lib.d << CODE
version (StdLoggerDisableLogging)
     enum isLoggingActive = false;
else
     enum isLoggingActive = true;

void doSome()
{
     import std.stdio;
     writeln("isLoggingActive: ", isLoggingActive);
}
CODE

cat > main.d << CODE
import lib, std.stdio;

void main()
{
     writeln("isLoggingActive: ", isLoggingActive);
     doSome();
}
CODE

dmd -version=StdLoggerDisableLogging -lib lib.d
dmd main lib.a
./main
