Ah thanks, I had missed the part saying that path and query
were ok to change. I think this part of the spec is very
controversial though, but I'll spawn that discussion to
another thread.

Sorry, it seems we are not talking about the same application.
Jonas referred to attachment pages in your bug database, which
I assumed would f ex be a page like this one:
(The textarea in this app is not created onload, it is delivered
in the server-generated HTML and thus is subject to form field
value persistence.)

What app are you talking about?

Certainly, that's why we are all here I guess :-)
Being able to do similar things as form field value persistence
and scroll position persistence, but for your own data, is the
purpose of history states, IMO.
