I mean, according to our documentation, users are required to provide full device XML they want to detach (see commit c6807b50). The reasoning behind is that even though today we rely on MAC address, tomorrow we can change that to a device alias or a combination of some other values and suddenly users passing just MAC address would break. I wanted to do something similar in ea7182c but it introduced a regression (fixed in c001eb5bbefd).
