SessionStateData contains the back/forward list, amongst other things.  The number of things it contains in the future might grow.  Most of these things will likely be desirable for people who think they actually just want the list of URLs in the back/forward list.

And if there's anything you don't want in there (I'd love to hear why you don't if there is anything), we could add filtering functions.

Having a freely mutable back/forward list in the WebKit 1 API turned out to be a mistake, and we're not interested in replicating that mistake in WebKit 2.  Treating a "session" as an opaque object that you can extract from a page and restore in to another page should be the only way to do this.

Note that the use case you gave in your initial report is entirely and cleaning fulfilled by this!
