It will be. Users won't get the new version until the header's bumped 
anyway.

Yes, but is this the best approach? I see you're taking advantage of 
`completion-regexp-list' and the fact that `all-completions' is 
implemented in C in `completion-pcm--all-completions', but if one would 
implement a completion function using an external service, in many cases 
this would mean a non-optimal amount of data to have to be transferred.

And a service's implementation of different completion styles could be 
just as fast, if not faster. Omnisharp has it already, so using it 
should make sense.
