No I don't think anyone from the opposition expects "special privileges" because they are the opposition. Contrarywise the opposition often gets opportunities to prove that they get less privileges than PAP people and this won't change no matter how low votes PAP is slapped with for doing that, until PAP is out of power.
The PA grassroots is simply the PAP arm in government. No where except in communist countries do you have a stat board that plays a grassroots role. Any application from PAP to PA is just a formality. There is a difference between a family member and one who is not. You would not allow a stranger to enter your house?
Tracy is right. If there had been no AIM, we can see the incompetency of the opposition. Unfortunately, we can't. Ditto for the hawker centre episode. The merchants association made a lot of noise, but we don't see merchants doing the same.
