Ability to have things flow in The nether

I was working on a super smelter in the nether the other day when I foolishly realized that the build required water and I was in the nether. I was thinking that minecraft should add A liquid that has the same functionality as water but is able to exist in the nether. I think it would greatly help me and several other builders out there. You could even do some thing like flowing slime or flowing honey if one so desired that being said I don’t really care what the liquid is I just want some thing to flow like water in the nether but not burn up my items like lava does, #Java
