Spells in 5e are largely just informational. They don't really do anything other than display neatly for us to read. I suspect LWD will need to change this significantly once HLO becomes a thing. They have talked about the ability for a player to use HLO to cast a spell on another player using the tool. So for this to work the ways 5e spells (all of them
) would need to be changed to make that possible.
So I suspect there is going to be change required here. On quite a large scale that I for one am not looking forward to.
