But very often -- at least in the traditional Linux distribution
universe I spend a lot of time in -- non-OSI-approved legacy
(generally non-copyleft) licenses appear *within* packages that are
portrayed or at least popularly conceived as being under another
license, whether that's a copyleft or noncopyleft license.
I think the value of 'mass legacy approval' might be to address the
criticism I've seen of the OSI apparently claiming that non-approved
licenses are not open source or validly referred to as open source
when no one could credibly argue that they are not open source. It
would also address my concerns about Van's interpretation. But I'm not
sure whether the effort would be justified.
