I remember one dev in particular (who is no longer around) being very vocal on the forums about extending duration on right click buffs. He and many others (including players) would argue it's not a big inconvenience to refresh your clickies when they wear off or on death and "if you want the buff, then click the item". Now most clickies have been replaced with passive AAs, and many ones that weren't became unlimited duration and persistent through death. I would say most people found this to be a positive change. If they did something similar for illusions I'd welcome it.
