Looks like a bug, somewhere. Somehow these new company
versions don't follow exactly the same protocol as completion-at-point.
Eglot aims primarily at that, since it's what's in Emacs proper. But
Eglot also aims at supporting Company in particular as fully
as possible.

Anyway, I don't have time to investigate this. The :exit-function in
eglot.el should be stepped through to understand exactly who's at
fault. And I don't think differences between servers matter:
clangd is likely following the spec correctly here.
