Bug#1102363: licensecheck: Exclusivly check for SPDX fields / Ignore every other license string

[Christian Buhtz]

Package: licensecheck
Severity: wishlist

Hello,

if covering/parsing SPDX meta data is implemented (#960665) please make sure to
ignore all other licenses strings.

Let me provide you some real world problem where this would be important and
also save resources of Debian package maintainers.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=960665

The "problem" here is that the whole project does offer SPDX meta data and
"reuse lint" is green on all files, which means the project is SPDX conform.

But one file "serviceHelper.py" does have comments about the license
history of that file. Some other licenses are named just of historical
reasons. License checker does consider that strings, too. That is the problem.

This is a follow-up from: <https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=960665#36>

Regards,
Christian Buhtz
