Like Stefan mentioned, you can already support Company through
`completion-at-point-functions'. Company will need to be installed
manually by each user, though.

See above.

But what's a "most likely completion"? When there's just one suggested
completion, then yes, we show an inline overlay. Otherwise, the full
list.

I remember you creating a Company issue, me writing you an example
snippet, and you going away seemingly (?) satisfied.

Have you had any progress using it? As long as we don't have
asynchronous users, there's really not much material for me to work with
to improve the API, as well as not much motivation.
