48+ # NOT IDEAL BUT NON-BLOCKING
49+ # we want to manually review and approve software using those licenses on
50+ # a case-by-case approach because it's debatable setup
51+ #
52+ # Those licenses notably include:
53+ # - Creative Commons versions (CC-BY is generally OK, but needs double-checking)
54+ # - LGPL, which is confusing between Lesser GPL and Library GPL and its many versions.
55+ # - Mozilla Public License (MPL) which is generally OK as well, but let's be conservative
