Signature and hashes have different use cases. A signature guarantees
that a person or organisation endorses a resource, as well as
guaranteeing the integrity. A hash only guarantees the integrity. A
signature should be given if a user is downloading software that must
be proven to come from a trusted source, e.g. a privacy suite or bank

Subresource Integrity could perhaps be extended to the signature use
case. I will write to the group. Thanks for the pointer!
