This sounds roughly like the implementation of server-side
state saving in the JSF 1.2 RI, as well as what's done in ADF Faces,
though not exactly, 'cause there's differences in the details (neither,
for instance, supports putting sequence numbers into URLs, just
hidden fields).

What exactly do you mean by "the serialized view is now really
serialized (this was not the case before)"?  Before, server-side
state saving (at least in 1.1 RI) was just stashing the UIViewRoot,
which dies for a bunch of reasons.  I'm gonna guess that
you grab the SerializedView object with StateManager.saveState(),
and then save off its two components.

Getting per-request state to survive <redirect/>, like Mario's proposing,
is a separate issue, as you say.
