This is being driven in industry by the push by US FedGov (via NIST) to have supply chain verification after the recent hacks.

POTUS issued an EO and NIST have been following up, leading to the promotion of schemes such as spdx https://tools.spdx.org/app/about/

Where I work is also required to start documenting our supply chain as part of the (new, replacing PCI-DSS) PCI-SFF certification requirements, which requires end-to-end verification of artifacts that are deployed within PCI scope.

So really, the arguments about CPU time etc are basically silly. The use of SHA hashes for artifacts that don't change will be a requirement for anyone building industrial software, or supplying to government, or in the money transacting business.
