Sure, you are right.

It seems a good solution.

Yes, but this involves MI process to be designed for that, and it's
not the case, right? This is, in case the retrieved information
exceeds some size it should be automatically partitioned in various
steps which are sent to the MI process one by one.

Sure, but what about when using just memory (as in db_mode=0 for
usrloc)? Also there are other modules (as LCR) which just use the
database to load initial values and later those values or their
attributes are modified in memory (i.e: LCR gateways status).
