I would argue that an Imperial garassion suppression policy was actually necessary because of how the empire came to be. The empire was converted into an empire from the republic which was a republic (hehe). The sudden conversion into autocary would of come as a shock to many planets which had experienced millenia of freedom, liberty and representation. The loss of this would of created resentment for the Empire across many planets. Without the threat of a near by garassion planets would of been more likely to openly rebel, knowing that they would have time to marshall an army before the Imperial fleet arrived. Knowing this it could allow planets that despised imperial rule to co-ordinate and openly rebel at the same time, eventually combinating in a repeat of the seperatist war (except this time the would be the good guys )
The garrassion policy prevented planets from open rebellion and instead we got a guerilla style(?) secret rebellion made up from individuals from many planet hiding in unhabited world in secret bunkers shifting from planet to planet with no real home base which made co-ordination more difficult for the rebels.
But the main problem with the Empire I would say was how it came to be. If it started out as small group of planets invading and conquering them and opposing Indirect rule it would been much more easier to maintain as you would be ability to maintain an elite effective army and a large empire at the same time and not have to rely on garrassion suppression.
Final thought. Empires must be born out of conquered provances or out of an anarchic state. The Empire took much from the people and planets of the republic namely power and freedom and offered little in return it was doomed to face rebellion in one form or another.
