yeah, I also can't see how to do pagination without imports, assuming 
the 3rd party store (ie. LDAP) doesn't have pagination support.

So then again, the question is if SPI should still have the option to 
support imports? Or maybe don't have it OOTB, but if customers start 
asking for pagination, we have the option to say them "ok, we will try 
to add it" instead of "no, you can't do that and there is no way to 
support it with current SPI" .
