Change behavior of killing nodes with same name

Any node which is already running with some name my_node_name will be killed if I run any node with the same name via rosrun and roslaunch.

Example:

# First terminal
rosrun rviz rviz __name:=rviz

# Second terminal
rosrun rviz rviz __name:=rviz

# First terminal again
[ WARN] [1529837879.313228883]: Shutdown request received.
[ WARN] [1529837879.313324710]: Reason given for shutdown: [new node registered with same name]

The only exceptions are nodes which are defined in the roscore.xml as explained here. My question is, can I change the behavior of rosrun/launch such that old nodes keep running and new nodes will be killed?

No, that is not currently possible.

Can you perhaps explain why you are looking to change this?

I just thought of it as a handy functionality. I have collections of multiple launch files for main apps and debug. It may happen when I start my various debug launch files that I have nodes with same names. Of course, I can use anon tag, but then I run multiple nodes which is annoying.
