chunked_insert_many with ordered=True and concurrency: raise a warning?

[hemidactylus]

What would be astrapy's stance when it detects this combination of parameters?
On the face of it, ordered=True and concurrency is probably not something intentional from the user.
On the other hand, astrapy in general strives to minimize its intrusion in the actual payloads.

Middle ground could be issuing a warning and letting the call go?
