What happened to the Thunderbolt/Concealed Explosives/Combustion Beam rework?

The question doubles both as genuine curiosity and to remember that these mods still didnt get any attention for like 5-7 years.

Mostly legit curiosity, as the last time I remember these mods being addressed was back in 2016, when Cannonade was accidentally released through transmutation and acknowledged when they removed self damage.  
 
They still do a pitiful amount of damage that is reduced by armor. The most use I can get off them is for status effects and for accidentally lagging other players with a Mirage/Fire-rate Hikou combo.

Ooh, I didn't know the issues had ever even been acknowledged, let alone fixes planned.  And apparently backburnered.

I didn't realize they were slated for a rework. I would like to see them bumped up. They have the makings for an incredibly fun, but not meta novelty mod. However currently they're just totally useless.

I don't know why they're not just flat percentages of damage dealt, rather than their own independent values.
