Can you please elaborate on "allowed, but deprecated" statement for "CLOSED"
and "Proprietary" (in their pure form) licenses? Will the requirement for
converting them to bespoke licenses become mandatory?
It is often used by customers creating recipes for their own software
components to simply set LICENSE to "CLOSED" and don't bother with
corresponding checksums or even provide a license text. I had worked on
some large projects with thousands of such recipes, where software is
either written in-house or come from tens of different vendors. I can
see this becoming problematic to convert all of them to bespoke licenses
with corresponding correct license texts...
On the other hand, I wonder if from SPDX/SBOM/CRA perspective it is required
to have such software components clearly marked as "Copyright John Doe. All
rights reserved" when the product ships, instead of simply "CLOSED"?
