since systemtap is still included in Redhat Enterprise Linux, I could
firmly say SystemTap is still highly relevant these days. So is
kdump/kexec.

IMHO, the most important part is the art of understanding oops message
and its related stack trace.

Or worst, what if the system just hangs....divide and conquer things
like disabling acpi, sysrq, might be the skills we need here.

Not sure if you agree with me here, but I just deliver my ideas.
