The problem is that the diffusion rate of helium through glass or epoxy and other glues and insulators can be quite high at room temperature (as a low temperature physicist well knows). So the container needs to be all metal with a soldered or welded seal.

Well, we are talking HDDs here. They used "all metal" containers for decades now anyway. Usually they had some filters and were not welded shut, but that is minor change IMO.

Making all of these openings impermeable to He is not a minor change and will likely significantly increase the cost of the drive.
