Unfortunately, the trident's biggest problem is that it's absolutely inferior to the spear overall, and even in this case, the trident has no advantages that the spear does not also offer.Already kinda is...
When making a melee weapon attack, a creature that doesn’t have a swimming speed (either natural or granted by magic) has disadvantage on the attack roll unless the weapon is a dagger, javelin, shortsword, spear, or trident.
[...]Even against a target within normal range, the attack roll has disadvantage unless the weapon is a crossbow, a net, or a weapon that is thrown like a javelin (including a spear, trident, or dart).
