As I believe was stated in the other topic you refer to, Khaled can be contacted regarding such requests and it is ultimately up to him whether or not to allow it.
The concern is that if mIRC is bundled with scripts, those scripts may be "dangerous" or the mIRC may be hacked. In either case, it can lead to a bad image for mIRC if people believe that mIRC is the cause of whatever problems those bundles caused.
