It definitely helps with control!been trying techniques like this lately, particularly to give more control of the reverb EQ/FX too. Like it a lot.
I've typically only ever had a drum bus and then mid-side EQ for the master channel.
But playing around with Bus sends has proven to really support a more surgical mix.
Another concept I like is having several different levels of Sidechain/Pump Compression busses.
-fast release
-slow release
-amount
All triggered by the same Kick can produce some great results and doesn't sound too monotonous in the overall mix.
