Mana Infused Metal ingots and Fluxed Electrum ingots don't have fluid recipes, when basically every other material used in omnium does, I suggest adding fluid versions of those just to make post-tank a little bit more consistent. Honestly not really sure why there aren't already fluid versions. I get that not having fluid solidifying gems is by design, and obviously fluid infinity ingots skips a ton of the endgame, but these are two fairly simple ingots that are just a bit annoying to have to still make the normal way post-tank. There might be a couple of other ingots that don't have fluid versions that probably should but I can't think of them off the top of my head.

Sorry for the delay in commenting on this issue but I noticed there was a PR targeting this issue made.

I have reservations about adding new fluids; in particular I'm not sure that it is an oversight that these fluids are missing. Because of that I had not scheduled this issue to a milestone yet.
