There probably wouldn't be much harm, but it probably wouldn't achieve that much, either. At the end of the day, the reason listed is pretty much moot anyway. How often would it really make someone think "Hm, yeah, that's a valid reason, they should have kicked me," when they wouldn't think that now? It just shifts things from "What? Why was I kicked?" to "What? Why was I kicked? I wasn't offline!"
I think it'd just lead to more confusion and more GM time spent explaining that the listed reason isn't everything.
I do think they ought to make their policy a lot more clear. Only half-serious, but maybe an active help window or something that pops up on your first kick and explains things a little better. :P
