But in the case of an area light, isn't the current behaviour of this setting to lead to a black mesh being visible in reflections, instead of being invisible?
Yes, a light source can only avoid to emit light, not become transparent (if it is not already, like all not-intersectable light sources: point, spot, etc.).

It is already possible to make a light source invisible to specular materials, there is a dedicated flag for visibility on diffuse, glossy and/or specular materials
Oh..sorry. You're right.
I've tried and it works. Good. And MIS is still there...at least the sampling seems the same of the "normal" area light.

I'm trying with my test scene..but I can't understand why you said that it become black...I've tested both with glossy and specular material and I can't see the black shape of the area light. Where am I wrong?

It works as far as I know

But I tested that on Linux, and it still shows the problem.
Is the orange juice scene working fine on your end?
Yes, it does.
