It's designed to ensure that authors can reliably use a name and expect to get the same result in any UA that supports that name. I'm not going to change the spec in a way that conflicts with that -- if the spec has to change, it'll change either in a compatible way (e.g. to match what was actually implemented), or in a way that doesn't conflict (e.g. by changing the name in the spec). > Note I'm not talking about Microdata in particular.
