IDK, I see matrimony rings rather frequently, and this issue comes up from time to time, actual marriages admittedly rarely, but there's a reason I brought up the rings mainly.

I doubt it's more work in this case than finding the items on a table and changing one small thing to allow them to be worn by all races/genders, I could be wrong, but doesn't hurt to ask the question.

This is the main reason I asked about changing the ring, not whatever the marriage procedure is, that may indeed may be more complicated, but it's allowed in 14, and while changing the full blown marriage procedure may not feel worth it to the dev team, I'd think the rings being changed would be a very small investment of dev time, and a good number of people would appreciate it.
