It's not appropriate for upstream to change this. On many systems just rebooting as quickly as possible in case of panic is the desired behaviour (think of servers).
I understand importance of collecting crash dumps but we can't change defaults in such a way.
And fo someone who would go into config file to set
could as well just add static arguments to his GRUB_LINUX_CMDLINE.

in Ubuntu we are working on making it easier to capture kernel
crashes. The system we use is based around kdump and it works by
triggering a kexec of a special crashdump kernel if the regular
kernels crashes. In order for this to work the normal kernel needs a
additional commandline option "crashkernel=".

Attached is a very simple patch that adds this option automatically if
kexec and makedumpfile are available.

If its not general enough for inclusion into the default grub2, may a
mechanism to pass additional kernel commandline paramters via some
sort of defaults.d/ directory would be the right apporoach? Then I
could just ship a config file in kexec-tools that looks like this:
