I'm wanting to reduce reflectivity of a specular glass as show in the first column of this image: Opacity seems to be more of an unnatural cheat since it messes the refraction if I use a value between 0 and 1.

I suppose there's a physical reason for the surface to have reflection even if set to 0. I suppose the artistic decision of less reflection is analogous to something like anti-glare coating. A lower IOR seems to be the way to go, right?

I tried to fiddle with the film width and index but I couldn't tell any difference.

Yes, you should lower the index of refraction.

I don't it's the right behaviour to reflect while reflection is set to zero.
For me it's a bug.
Maybe the inner face of the glass is reflecting ...

You coudl also use a fall off node into the secular channel.

You are right. Back faces keep the reflection 1 regardless of the material setting while camera facing polys behaves as one would expect. Seems indeed like a bug or is it? If so, hope it's easy to fix.
