That's precisely the point of using tabs for indentation: you don't need to fight over it, because it's a local display preference that does not affect the source code at all, so everyone can just configure whatever they prefer locally without affecting other people.
The idea of "skins" is apparently to push that even further by abstracting the concrete syntax.
Do you mean that files produced with "wide" tabs might have hard newlines embedded more readily in longer lines? Or that maybe people writing with "narrow" tabs might be comfortable writing 6-deep if/else trees that wrap when somebody with their tabs set to wider opens the same file?
