I think a copy of the GPL alongside source code (e.g. [1]) is ambiguous. And the article you link mentions “confusion” in the URL, “foggy” in the title, and “ambiguity” in the subtitle. I agree that you can, like Fedora, decide that you are comfortable enough with one interpretation. But I think Gary has volunteered himself for the “I'd write partially-concluded license expressions, but there's no syntax for it yet” camp [2]. The FSF itself is unwilling to commit to a public position on this situtation (as far as I'm aware). So I think there is likely to be a substantial set of license-expression authors who are unwilling to claim a complete conclusion. Is this point still under contention? If we accept a substantial set of partial-concluders, the SPDX needs to decide what to suggest to them. Folks using SPDX documents can already use comment sections, but those are unstructured [3]. And folks using bare license expressions obviously don't have access to the SPDX-document comment field. We can tell them: a. That they cannot pass the partial conclusion along, and can only bail out with NOASSERTION (I've filed [4] to add that to license expressions). b. That they can pass the partial conclusion along, using: i. an AMBIGUOUS[-VERSION] operator, or ii. an OR-MAYBE operator, as discussed in [5]. I see no upside to (a), but I'm not an SPDX maintainer. I strongly prefer b.ii to b.i, as discussed in [5]. The OR-MAYBE operator (b.ii) is completely independent of how the or-later business shakes out. The AMBIGUOUS[-VERSION] operator (b.i) overlaps slightly, because you'd have to choose which GPL short identifier to use with AMBIGUOUS-VERSION. If (b.i) has no surviving supportors, we don't have to worry about that at all.
