What Jutsu’s do you feel should be Kekegenkai but aren’t?!

This is a list of jutsu

1. Expansion jutsu

2. Suigetsu’s Hydrofication jutsu

3. The Raikage’s lighting cloak: I feel like it makes sense for it to be a storm release technique instead of shooting the energy you wrap it around you creating a cloak similar to jinchuriki chakra cloak

4. Steam imp jutsu: Y’all remember the steam imp the jutsu of the second mizukage that expands over the course of the fight until it eventually explodes.Doesn’t that description sound like boil release a mix of Fire and Water. I know Naruto is primarily for kids and showing ninjas getting third degree burns might be took graphic especially if they’re still alive and walking around but steam is can be pretty hot. Headcanon the steam imp could be the reason why the second Tsuchikage wears those bandages. Could you imagine the damage Mei could do if she had excess to that Jutsu. Boil release is so underutilized even in places you’d think it should be used Kishimoto doesn’t use it. Steam imp should be a boil release jutsu
