Why they should enable core dumps, if they don't know what they are and
that they exist?

What has a core dump to do with debugging code? Every process' core can
be dumped to disk. You don't need to enable special debugging options
while building to get a core dump.

So, you should get familiar with the features of your tools. gdb, for
example, has the possibility to use detached debugging symbols. The
binary is the same as the one you get after strip, but you get a second
file where gdb reads the debugging symbols from. And you don't even need
to place both on the same machine to inspect the core dump.
