Indeed, it does seem relevant. But it doesn't define a completion table 
in the standard way, so the question is moot.

I mostly meant the possibility in the Project API. But yes, to make it 
really useful, completion code needs to interface with external tools 
better as well. It's also one of the blockers for deprecating 
company-mode's own backends.

I think you mean completion-try-completion and 
completion-all-completions. How will this happen? Will these functions 
become generics? Do we expect the external tools to honor 
completion-styles values anyway somehow?

It would be great if you could file a bug and describe your current 
views on this subject there, so it's not buried in this discussion.
