Your only motivation to put the thai name into name=* is that the thai version of the name should be rendered on “default versions of the maps”. Or am i wrong? What should be the use of this “default map version” if germans want to read german and thai-natives prefer reading in thai? Who should use this “default map”. Only www.openstreetmap.org will use it in future i guess. Everyone who wants to provide useful information will let the user decide what he wants to see on the map. And this is one of the core buisinesses of the rendering software. This is why i call your suggestion “tagging for renderers”. But we should not waste our times with discussions about terms like “tagging for renderers”. Sorry, i will try not to use it anymore 
This is just a guess. Maybe, maybe not.
Some companies invest more into their representation on the internet, some invest less. But all invest into labeling their shops, printing advertising in newspapers and mybe in TV-commercials. If a Mercedes-Benz shop in Thailand has a big label “เมอร์เซเดส-เบนซ์” and not “Merceds-Benz” than you would be right. I do not know a Mercedes-Shop where i can go and have a look. Do you know one? Maybe Mercedes is a difficult example, because they sell “high class products”. They surely fear loosing customers and invest much money into intelligent marketing. The best “default” value for representing a store of Mercedes-Benz on a map would be a small icon with the Mercedes-Star on it.
