The problem is, the processing would ideally be done in the transmitter, not the amplifier. There's no reason it has to, but transceivers are already so full of digital stuff, a little more wouldn't matter. For code adepts of the digital sort, writing a routine that would decrease drive when two conditions existed:

ALC feedback level rising between two set points at a certain rate, and then
ALC feedback level reaching a certain level

doesn't seem so complicated, but I am not a code adept of that sort. 

What a great selling point that would be for Ickensu: "Smart ALC."
