That's already possible.  The client can just fetch the
subschema subentry from the same server would provided
the entry.  Of course, if the application uses the
LDAP sync API with chasing enabled, they've chosen to
give up some information (e.g., such as which server
returned a particular entry).

I think it would be more desirable to extend the API such
that applications could query the API for information about
the source (server) of each entry it is provided by the API.

No.

You are welcomed to submit a patch for consideration.
