The premise was that computing a graft is usually quicker than transferring it, which is why they have #:substitutable? #f. I don’t think it would be reasonable to have a switch to toggle #:substitutable? because that would make .drv depend on external factors. However, when copying things around, you can still do: ‘guix copy /gnu/store/…-xyz’ and that’ll work fine, whether or not it’s a graft. But maybe that’s not a satisfying answer for your situation?
