Thomas and Greg may have decided not deprecating the old identifiers [1]
to avoid modifying thousands of files. I think it was expected the SPDX
to mark them as equivalent? But I'm not entirely sure if this is the
correct approach though as SPDX marks them as deprecated as I mentioned
earlier.
Thomas, Greg, are we using any specific SPDX version for kernel license
identifiers? Why the new identifiers where amended as valid and not
replacing [2] the old ones? Was it to avoid replacing all files with the
old id?
