The issue isn't whether or not preexisting alternate methods exist, it's whether or not Mirc will have this feature included in it's core.
If you read the thread you'll see that the poster I replied to was suggesting there are no viable alternatives; I wasn't the one who brought it up.
I'd guess that the only reason it hasn't happened yet is Khaled has other things on his TODO list which take higher priority.
You're probably right.
