Most embedded hardware has no easy way to send/restore core dumps if JTAG is disabled.
And even if it did, a good chunk of debugging involves running the system live in the target environment and looking at traces. Eg. "the device doesn't work properly when on the customers wifi network because their router responds to ARP requests too fast and we miss the response packet because we're still busy reconfiging the radio from TX mode into RX mode"
