I voted no. I don't think it's necessary, but then again, (in my style) it's a huge part of Aikido so without it are you stil doing Aikido or just a particular part of Aikido? Isn't Aikido the whole of taijutsu AND bukiwaza? Weapons training might be in there just to help your taijtsu, but I feel there is something more to it, than just that.
It's sort of like beeing able to drive a car superfast and supergood, but not beeing able to go in reverse. You could win every race, but you'd suck at parking when going to the mall... Are you stil a good driver? Would people think you were?
