[adelie-project] Licensing update policy

I recall reading an article or email on LWN a few weeks ago concerning a distribution's policy for re-auditing licenses for packages and I wanted to determine what we should use as our policy. As it stands, we obviously audit the license for each new package that goes into master - but when should we re-audit the license of a package? I think a reasonable suggestion would be on every feature update, since every feature has the potential to bring in code with a different license. As a caveat, maintainers should also be vigilant for notices of licensing changes in the changelogs regardless of the type of release. Any thoughts on this? Max
