For obtaining a raw picture of some device state, there is still gdb.
What this feature is targeting at is a refined view, something VMState
already represents as it (in the absence of bugs) contains the complete
persistent state, and only that.

Once we have QOM in place and also sorted out how VMState 2.0 may look
like and how it can be extracted from or expressed within the device
model, we will probably change the internals of this feature again.
