The problem with it not being portable is it makes the cauldron completely useless. The thing costs 700 hammers, so it's only reasonably buildable in an established city with good production. The kind you'd be an idiot to let come under direct attack in the first place.
Single-player related commentary, only.
Basically the same problem effects the Soul Forge, but a portable forge might strain the bounds of credulity.
