Could bash be specified as an input, and that used instead? This would mean that the behaviour of the package is more isolated from the environment. For example, on non GuixSD systems, /bin/sh could be something other than bash. But, if the numpy package depends on some bash in the store, and uses that, then it would be isolated from this. What do you think?
