Besides defining these two tables, we should also say which one is preferred.
That should be the default and people who don't like this would be able to
make it work the other way. That would result in applications working
properly together when the user didn't set anything.
Since some characters are very hard to read when they are single-width, it
might be best to have the default use double-width characters in places where
there is ambiguousness. At least you will be able to recognize the character.
But there are probably many other issues that matter...
