Th small things that add to immersion/roleplay is important.
Having a diety choice for all PCs so it triggers the dialogues and just, more building characters is important. If the triggers are already there for clerics, it makes sense to open them up to all characters (espec as the second(1st do we count prologue?) NPC you can recruit, is cleric).
It's a dnd thing too. To have all the values for roleplaying, not just the ones mechanically relevant.
Should definetly have all the clerics goods + a non observant option
Even if it doesn't trigger the deity choice dialogues it ought still be there for RP
