if I’m first at the light I pull up far enough so they can get around me, but not possible if I’m second, etc.

Doesn’t this sort of resolve the issue? If you are second in line it isn’t like you are holding up the line, if they guy in front of you turns right then you can just move forward enough to let everyone through, if he isn’t then it isn’t you holding up the line.
Either way, it is a courtesy to let people turn right, but not an obligation. If you feel comfortable moving to the middle line you should do that, if doing so means you’re going to have to get back into the right lane on short notice then I wouldn’t bother, since you’re basically driving more erratically (always a bad thing).
Something to bear in mind here is that the lane really is a driving lane. That is what it was built for, to be a third driving lane, and it would be ridiculous if people slowed down the traffic by all cramming into the two other lanes. If the planners thought that two lanes were sufficient then they would have made the third lane a turning lane only, clearly they felt a third lane of regular traffic was necessary.
