Re: Combined version of LGPL + GPL 3.0
Sebastian,toggle quoted messageShow quoted text
When you say "Nothing similar had been brought up before" are you talking about the inclusion of GPL text inside the LGPL one?
Because the whole thing "LGPL is an exception" and "needs GPL text" has been discussed at somewhat length:
(and then on a Legal call, as stated).

Things have been moving really quickly on this, so I think I ought to give some background! I believe this to be a complete summary, though of course I don't know of the content of the Max's correspondence with the Free Software Foundation.
Last Saturday I was looking through the list of issues on the REUSE tool repository and noticed https://github.com/fsfe/reuse-tool/issues/86. The issue described is that the LGPL requires the full GPL text to be present for proper compliance, but REUSE does not allow unused license texts to be included in a given repository.
It occurred to me that this could be resolved in the SPDX License List instead of in REUSE - the entire GPL-3.0 could be added in an optional section below the LGPL-3.0. This would mean that:
- No SPDX License IDs would change. LGPL-3.0-or-later and LGPL-3.0-only
would still refer to a standalone license, and users would not need to
use the 'AND' syntax in SPDX documents or license expressions.
- Users of REUSE would simply need to download LGPL-3.0 via the REUSE
tool. The tool fetches the SPDX License List's text, including with
the optional sections. As a result, no further action would be needed
to comply with the LGPL's condition that the GPL be included.
- License scanning tools following the SPDX License Matching Guidelines
would not be affected: as the entire GPL section is surrounded by
<optional> tags, existing occurrences of the LGPL text would still be
matched as LGPL, as has been the case thus far.
I took the time to review the previous discussions about the LGPL in the past, both on SPDX's and REUSE's mailing list archives and GitHub repositories. Nothing similar to had been brought up before, as far as I can tell. Hence, I posted my idea in the reuse-tool GitHub issue and waited - not for long as it turned out!
Earlier this week, both Max and Matija agreed on that issue that it would be a good solution, and Max contacted the FSF about it.
Fast-forward to today, and I was just about to write to you and Steve Winslow to ask for this to be put on the agenda for the next Legal Team meeting. At that point I saw Max's note that the FSF had already released the combined text! Apologies if this caught you by surprise, Jilyane; the FSF's speedy publication certainly did for me! All my correspondence with Max is publicly visible on the aforementioned GitHub issue.
Sorry for the somewhat long post - hopefully I've been able to describe how this idea satisfies the REUSE requirement, whilst addressing the concerns about backwards compatibility for those using the existing identifiers, both for license matching and for licensing their own repositories.
If you or anyone else has any futher questions I'm more than happy to answer them here :)
