What? By pushing back against a customer who wishes to be addressed as Mrs, you are invalidating their own sense of identity under the guise of doing them a favor. It's paternalistic and infantilizing.

EDIT: Oh wait, "customer" here may mean "client", as wilg pointed out, ie. the person asking for the form to be built, not the person filling it out. That is likely the source of this misunderstanding. I still don't see the harm in providing both Ms. and Mrs./Miss -- some surely prefer Mrs. and there is no shame in deciding you prefer "Ms."

I took this entirely as a conversation between developer and "stakeholder," be that client, employer, whomever, but not the end-user.

I've built many such forms, and all of them have included traditional forms of address. I may build another with traditional forms of address, but I certainly have no problem discussing the subject without laughing the idea off.
