"non-standard" seems very ambiguous to me. If this is targetting HMDs in
particular, perhaps we can borrow a term from that. Without being really
familiar with that technology, a quick Google search suggests that these
devices are commonly referred to as operating in "direct mode". Perhaps
a boolean "direct-mode" property would be less ambiguous?
