AFAIK, only with the default panic=unwind mode. With the panic=abort mode, it aborts the whole process instead of unwinding.

panic=abort is only intended for embedded stuff, I think.

Nope, it's intended whenever you want this semantic, and do not want to pay for landing pads. Embedded is a common case where this is true, but it's not exclusively for that.
