Exactly! How much effort has been spent on UI kits already and we still have very few options, most as you say, half-finished!
If only people had as much energy to help finish/improve existing, usable UI kits instead of re-inventing their own just for the glory of it.
I have no doubt this effort will end up in the same exact way as the xi-editor (https://raphlinus.github.io/xi/2020/06/27/xi-retrospective.h...) - a Rust text editor - did: huge amounts of work spent reinventing the wheel, one or two minor original contributions, but ultimately, ending far short of its goals and not delivering anything.
