Isn't that what Wren requests? If we do nothing to the target when the GDB connection is dropped (killed GDB or lost connection) and resume the target on the low level packet "$D#44" (detach).
However, it's not strictly specified that the target *should* resume when GDB detaches. "Detaching from the target normally resumes its execution, but the results will depend on your particular remote stub." The documentation for the "detach" command isn't really relevant since it doesn't deal with remote targets specifically (it also says that quitting GDB will *kill* the running process, not resume it).
