I think the word choke is inappropriate to Aikido. Why cut off the air, the windpipe? Neck holds would be a better concept, a version of close in iriminage would be just as effective. Learning to hold with a circle too. Lots of ways in Aikido without blocking or cutting off the windpipe.
I would say good practice in Aikido would be to try such positions as would be chokes and find what is more appropriate, less damaging and yet more effective. The way of Aikido no?
