Yes, it's only now a feature with Vim 8.2.

Edit: Or maybe only "officially" now with the new floating window API instead of having to roll your own code.

In any case I really appreciate what Neovim is doing to push Vim into adding features. I hope one day they converge into a single tool.

I don't know the details of 8.2, but floating windows have been possible since a long time (e.g. YouCompleteMe https://github.com/ycm-core/YouCompleteMe)

Completion popups were already available, but were specific to completion. They couldn't be used outside that context.
