Is it possible to scope ServiceStack.Text.JsConfig settings to just your library?

This functionality was missing in ServiceStack.Text so I added a pull request for it.

Basically now if you wanted to scope your config settings you can use the following syntax:

using(var config = JsConfig.With(new Config { DateHandler = ... }))
{
}

And the values will no longer be set once the using block goes out of scope, its ThreadStatic as well so won't affect other threads.
