Don't enable Telepathy by default
Please consider disabling Telepathy support by default. Empathy hasn't been part of a typical default GNOME desktop in a while. GNOME Online Accounts stopped offering any Telepathy support with the 3.30 cycle.
See https://mail.gnome.org/archives/desktop-devel-list/2017-October/msg00040.html and https://bugzilla.gnome.org/795322
Maybe this should have been done for 3.30.
