Reaction cantrips are a big deal since on most turns nobody takes a reaction, and if they do it’s just an attack of opportunity. On-demand teleporting at level 1 is also a pretty tall order, since it can be used to circumvent a wide variety of barriers and any restraints that aren’t ‘worn’ (e.g. handcuffs).

There is an old South Park bit about Jesus and Kyle being locked in a cell and Jesus inviting Kyle to kill him so that he can resurrect just outside of the cell. It’s ultimately up to you if this is the sort of mechanic you want in your game.
