MoroS  filed a deletion request for electron-bin :
Now that electron is in the community repository there's no longer any reason to keep this package. It only did repackage the official binaries and community/electron does an even better job of providing them. All AUR dependencies on this package have already switched to electron.

Request #6259 has been accepted by Dragonlord .
