When you fail at something... change its name and say that's what you intended it to be in the first place.

Simple! Its not xr, its MR (Mixed Reality). MR is used by many in the industry and is getting used by techies and companies, now please dont bring on xr stuff and add to the confusion!
We could have a spirited debate about this (uhh, are we about to?), but let me start by acknowledging that you're mostly right. The whole of the spectrum is indeed "mixed reality." At one end of the spectrum is AR (see through lenses, some things added to actual reality), and at the other end there's fully occluded VR. Everything else is somewhere on that spectrum. So...yes, it's all technically "mixed reality."
But in practice, calling *everything* on the spectrum "mixed reality" is problematic. Let's say I'm describing the Oculus Rift. Do I call it a "mixed reality HMD"? No, because that would be confusing. If I'm trying to explain what it is, I have to call it a "VR HMD". But...there are also HMDs that do mixed reality, which is to say, they mix elements of the virtual and real worlds. I would call that a "mixed reality HMD".
In other words, the term that possibly most accurately describes the whole of the spectrum is BOTH a general term AND a specific one. #nomenclatureprobs
I like "XR" because it's ONLY a general term. And the "x" is kind of like a variable, sort of like (A, V, or M)R. And it's a cross symbol, as in a crossing of realities. Eh. Fun.
