If you use a time travel debugger (rr-project.org, undo.io - where I work, or Microsoft's WinTTD) you can generally just record an application to a file and debug it (with full fidelity) somewhere else.

And you don't need a full debugger setup on the target machine, just the recorder binary.

Gives you the possibility to have a proper debug experience without having to set up debugging that somehow works in a live k8s pod, or connects through special firewall holes or somesuch.
