In any case, hidden does not equal no line of sight, so even a hidden trap is still within line of sight and therefore subject to the spell.
Correct.
I would prefer it to being a Concentration(1 minute) spell though, with a radius effect (maybe 30'), blocked by walls/doors though. Then it might be useful. As the point about 'treading on a Rogue's toes' that someone made earlier is not applicable, with a Rogue in the party a Cleric is unlikely to consider the spell anyway.
