No, not alone. I mean, they have reasons, I'm just not sure they outweigh the benefits.
It all goes back to Druh wanting this to be an integrated streetcar like line that was not obtrusive. They wanted low stations that wouldn't be as large an impact, as it was going to run at street level for the most part. But then scope creep hit, it went underground, grade separated for 95% of it, and no one thought to re-examine whether the low floor plan still made sense. At least that's how I see it.
I also dislike them because instead of one flat level floor, you have more impediments.
