I'm not defending the decision to include language-specific options, I was just trying to explain why they could be regarded as necessary. Email knows no national or cultural boundaries, and users in any one country or language zone have contacts in other
countries and language zones. Apart from that, you can find statistics like Chinese ... is the third most-spoken language in the United States ... Over 2 million Americans speak some variety of Chinese.
You'll note that the Yomi fields now appear at the bottom of the list of unused Name fields, where you can cheerfully ignore them, just as I ignore Statefor my contacts that don't live in one.
Microsoft should work out easily ... which country I am from and what language I prefer
Both of those bits of information are part of your profile. They still don't say anything about whether people in your contacts list have Yomi names.
