I am not married but I think that whatever tradition may say if Prince William’s decision to not wear a wedding ring is ok with his spouse, then that is what should count. Maybe if he took up some public position on marriage, etc. and pushed the issue, then maybe wearing a ring despite his preferences might be called for, otherwise it is a matter between him and his spouse.
Naturally personal safety is important but that is an external matter to this interpersonal decision between him and his spouse. I doubt that most any spouse would prefer that their loved one risk being maimed, in situations where it is a significant risk, just for the show of committment.
