Believe 2:1/18:9 is the standard for 4k production. If the TVs available can't display the full height because its a wider picture then it will always have black bars. whether 8k TVs will "fix" this remains to be seen.
For years films/movies were made typically in 1.85:1 or 2.35:1 aspect ratio. This generates massive black bars top and bottom on a smaller screen like a TV. TV is just sort of catching up to that. Before widescreen was a thing a lot of this when seen at home was the so-called "formatted to fit your TV" bodge, which just boiled down to a 4:3 cut-out pan-and-scan.
18:9/2:1 is no more wasteful than 4:3 material on a widescreen TV, surely?
18:9 is the happy medium of 1.85:1 and 2.35:1 Given you the width of 2.35:1 without losing the height of 1.85:1
