FWIW the "in the cloud" is how Microsoft has stored symbols for most of the Windows stack for at least 10 years.
Basically, debuggers can download them on demand - kind of useful if you find yourself in WinDBG (which I swear is where I've spent the majority of my Windows using time in the past decade).
As I remember, tools such as Apport (developed by Ubuntu, heading toward Debian - see the python-apport package) store the symbols on the machine that decodes the generated report, not on the machine where the segfault happens.
From memory, the data retrieved after the crash isn't a full core file, bit I suppose it's enough to obtain a backtrace.
