So you can't submit this until we've applied the final version of that
patch, because you have no idea what the exact mechanism is going to be to
enable dumping of your state, and therefore you can't code to the API
that enables your part of the dump.

The way that you rush your work is irritating, let things run their
course, in as much time as it takes.

And frankly there is no rush on this, as the next merge window for
new features is several months away.
