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

If it where done this way, yes of course you're right. But it is 
not, please take a look a the source first.
