Toll the Dead tends to be a much better damage cantrip for clerics at low levels (more damage and WIS save instead of DEX save, which tends to land more against low-level enemies), but it's from Xanathar's, so I expect we won't see it.
Other than that, the cleric cantrip list isn't spectacular for combat, which means clerics may need to be a little more conservative with their spell slots, especially at low levels.
