IMC or VMC?
IMC, configuring near 1000' would result in the crew still completing checks close to or below 1000', and possibly missing ALT crosschecks for CAT I approaches. For VMC, depends on the airlines operational procedures, and what constitutes a stable approach. For an Airbus, the ATR works nicely managed so flaps for the speed is a nice option, that means having gear out. As far as drag goes, as you get below 2000' some drag is going to be necessary to manage speed, and gear does that nicely. For a Boeing, the AT system is handraulic so having flaps out and dropping the gear works fine and doesn't risk the Airbus ATR overriding to reduce speed and disconnecting the ATR close to the ground. In all cases, the time from your target speed reduction point to passing 1000' is about 35-45 seconds, and the speed reduction is about 20-30 kts, about 1kt/sec which is not excessive, but also needs to be monitored. KISS would increase operational safety and minimise visits to the QAR process managers office.
