I would like to see an easy to use API for popups in Emacs. However it
may be a bit early to add Posframe.

I recently made a small package, Corfu, which uses Company-like popups.
I considered using Posframe but went with overlays (which are are poor
substitute for real popups), since Posframe still has a few bugs.

For example the internal border is not drawn correctly
(https://github.com/tumashu/posframe/issues/74). Furthermore the child
frame creation is slow as has been discussed in the thread about hidden
frames. Are there Emacs bug reports addressing this?
