While that may be true in the consumer world, it would make a lot more sense in the world of acquisition if we all used the same terminology specifically to avoid what you have just mentioned. And lest we forget there is UHD 1 and UHD 2!
So 4k and UHD should work as shorthand for us for now. I think/hope.
I'm not going to agree with you on this one. Unfortunately, as professionals, we will continue to have to deal with people coming from the consumer terminology, including producers. Using "4k" to specifically and solely mean 4096x2160 is not going to result in effective communication, since the term does not have universal agreement.
