Historical reasons and because that is what killall5 support, as I
noticed you discovered shortly after you sent this email. :)

Would need a change in the interface and behaviour of killall5, or
perhaps it is enough to do 'ps -ef' or similar?  Not sure if it is
useful in non-debugging sessions, though.

Fairly easy to do, but I am not sure it is a good idea.  I would need
to have some idea about how often the SIGKILL part is reached before
doing that.  Do not want to slow down the shutdown only to make
debugging easier.

Happy hacking,
