I have had many gearboxs with the loose bushing syndrome and never noticed any ill effect generally.
Cranked really high FPS and poor shimming may cause the bushings to turn in the hole but in my experiences even when I bushing was loose in the hole it didn't turn in the hole with the gears providing the gearbox wasn't shimmed too tight.
So if its not turning in the hole its not going to make the hole bigger. But like I said you have to ensure you don't make it too tight with the shims or it might.
