Is GGG ever planning to add vaal skill bonus on enchantment?

Hi, I am thoroughly enjoying vaal ground slam build (even after the heavy nerf on VGS and chill of corruption on 2.1 patch). The enchantment on the helmet piece is suppose to be very skill specific and requires you to do multiple labyrinth run do obtain the stat that benefits the skill you use in your specific build.
However, I've noticed that there is actually no bonus for vaal skills in the enchantment. This really disappoints me that GGG are nerfing vaal skills to the ground (I hear vaal spark also received heavy nerf). Vaal skill builds are very strong. But they are also quite expensive. They only work with certain and specific build and set up for them to keep up with soul charges (which now is much more difficult due to the nerfs).
I was wondering if this enchantment was ever to be made, but is still under tweak, or GGG never wanted vaal skill to be used as main source of damage in any build?

I might be wrong, but I thought a regular skill enchantment, ie burning arrow damage bonus, will also benefit vaal version of the skill (ie, vaal burning arrow) ? I will test it out today.

Thank you so much for the clarification !
