Does this mean Godot doesn't crash if you enable airplane mode while downloading export templates?

Correct, I tested this and Godot appears to timeout in the background then display a message that it will download in the background.

However I just tested this again, i.e. put Windows 10 in "Flight Mode", in the hope of getting a screenshot and it was unable to continue the download, I went to cancel as the message was not appearing and Godot went through a "Not Responding" phase, recovered and showed the message (after it had frozen):
