Variable train lengths and car types could make it so that it would be difficult or impossible for some trains to have the train doors stop at the platform doors.
At-grade operation of the system could make for some even more precarious situations for pedestrians and/or vehicles on the cross streets. The platforms are now integrated into the sidewalks themselves (the sidewalks ramp up on the new and soon-to-be-finished 7th Avenue platforms). The barrier kind of goes against the design concept of the new stations. Also, the platform doors could see frequent technical problems arising from being exposed to the elements at-grade, as opposed to being underground at a subway station.
Buses and emergency vehicles also use the 7th Avenue corridor, which would make operation of the platform barrier doors need to be operated by the LRT operator. To be honest, I'm not sure if that's how it currently works in other places, but if it isn't, that could pose a problem.
With the introduction of low-floor trains and platforms on the future Southeast and possibly north central lines, it makes no sense at all for those stations.
I could see the stores and businesses that now front onto the platforms themselves not liking it due to reduced visibility and perceived access/egress to their establishments.
Lastly, these types of platform barriers just aren't that common, even on busier metro systems in say Montreal or New York. I can't think of a single LRT system that has them.
