You're probably right for the case where people start the program from
GDB, but I guess that when people attach to an already running process
they typically don't want to kill it when they're done with debugging.

That said, it is probably a bad idea to have different behaviour for
"run" and "attach" in this case.  Let's throw the switch after the 7.3
release and see if people even notice.
