This doesn't sound as a good name given the existence of: https://vmware.github.io/photon/
Granted, in the context of atom and electron it makes sense, but still.
Also an unfortunate name clash with the Photon and Electron embedded boards by Particle...
At this rate I also foresee a clash with Phonon and Plasma from the KDE project.
Yeah, as someone who works with Electron, the naming is often frustrating for doing Google searches. Wished they had stayed with atom-shell for that reason.
