I honestly don't see a single reason why pumps shouldn't work with superheated fluids, or why there wouldn't at least be some separate entity with that capability. While it makes it more "challenging" it doesn't improve any aspect, you don't get more interesting builds or setups just because you cant extend a refractory pipe line infinitely. Very disappointing, should at the very least be a toggleable option, especially because this single thing has lead me down a rabbit hole trying to fix it in your code or remove your mod altogether (which is a giant hassle because you have to replace all pipes).
