It looks like the source of the problem was this change in the code:
Revision 499764 - (view) (download) (as text) (annotate) - [select for
diffs]

* Kate will export the PID of the instance in the environment variable
KATE_PID. You can use that to do some initialization in your ~/.bashrc
file for example, if you like to open files in kate from the built in
terminal:
# If we are running in a konsole in kate,
# $KATE_PID is the pid of that kate application instance.
if [ -n $KATE_PID ] ; then
# open files in this instance
alias kate="kate -u -p $KATE_PID"
# allow creating a new instance
alias kate_newinst="`which kate`"
fi
The discussion continues and recognizes the difficulty in getting the
old behavior back.

Always follow the configuration option for chosing a session when none
is specified.
I commit this, since I can't see how else we can enable old style
behavior easily. The 'new' behavior can be achieved by keeping the
default configuration of starting a new session.
