I was planning to include this in the 3.2 update, but after some attempts, it's not straight forward to support. Considering usually dedicated mesh lights will use the Emission shader, since they don't need a visible BSDF surface, I'm thinking supporting this is not a high priority. In cases where it's useful to have Emission as part of the BSDF shader, I don't think these are often treated as primary light sources that contribute a lot to the scene, but more of a visual effect. Closing this for now, but happy to hear feedback if this feature is important to someone.
In 2.91 (or 2.92?), the Principled BSDF shader has a new Emission Strength input, and can thus be used more easily as a light source. Gaffer should detect this.
