A core dump facility would be nice, but I think it is complementary to
the linenumber information in stack traces; not a replacement for it. To
be able to core dump, the storage driver stack must be loaded so disks
are accessible. For all crashes before this happens, core dumping is
useless. Also, I don't always setup a system with a debugger because it
is difficult and sometimes it helps a lot just knowing the line of code
where a crash occur.
