If that work, jwchat is broken, as the setting on disk is supposed to
override the debconf value and preseeding like that is only supposed
to work for the first time installation.  In other word, if this work
then jwchat is broken and should be changed to make sure it do not
work.  I even believe such behaviour is RC as it is against Debian
policy (10.7.3 Behavior) to behave like this.

For configuration changes like the one above, the debconf frontend
need to ignore debconf SET calls done by jwchat and provide its own
answer (the new hostname) no matter what the package read from disk.
I am not aware of anything implementing such feature at the moment,
and not quite sure it will work.
