It would be shocking if HTS manufacturing research did anything other than accelerate. If there are fundamental physical limits to run in to then they are very far away. This is deep in the engineering limited area. How much abuse from strain and radiation can your HTS handle? The better your answer at a cheaper cost, the smaller and more powerful of a machine you enable. Humans know how to make pretty strong steel, so the superstructure won't be a limiting factor for a while if ever. Making HTS tapes and divertors that can handle what we ask of them are the material challenges. There is room to be clever with physics to lessen the divertor problem.

Plasma "beta"s are only a few %, so for a few atmospheres of plasma pressure your magnetic cage needs to be like a pressure vessel that contains hundreds of atmospheres. And with large holes poked through it for access. If you look at CFS's magnet test from last summer, there's a huge amount of steel.
