It's not "unfixable" as Panda has showed... and has even done himself (he fixed it on his own in the video you probably didn't watch...)
That being said there is very good reason for this to be fixed. There have been multiple occasions as a map maker that I have needed an invisible mob of any size to detect player clicks for instance. The main thing to remember is slimes are exceptionally good for map making because of the fact they can be any size. That is so powerful and the only problem at the moment is you can't use them... Because whenever it gets near a player the player dies... Not great as a map maker.
Also might I just say, it doesn't make any sense. Every single mob does damage through AI except slimes... noAI stops every mob damaging you... except slimes. For consistency this should be implemented. The fact that many people have suggested it just goes to show that even though it does not fit to mojang's definition of a bug, to the rest of the community it is. Therefore, at least in my opinion, it should be fixed or another work around added.
