SysRq was selected because you are not going to press Alt-Printscreen-X by default. I'm not sure if F10 is similar level of "impossible to press by mistake", altrough holding up F10-B is likely not too common. Maybe it should be some combination for chromebooks? Leftshift-rightshift-F10-key? Ctrl-alt-del-key? :-).
