Hi Richard & Gary,

At a time I am requested to align various projects and the EC publication
office license lists (data sets) I am still uncertain about the SPDX policy
of creating "actual" SPDX identifiers for "future" or "later" licenses.  I
shared concerns with Jilayne but be sure that this is not done for creating
some controversy, just to check that the SPDX policy is well understood.


   - Adding "or-later" (and much more rarely "-only") is indeed a frequent
   licensor practice because recommended by some license steward. For example
   if you search Google for "Licensed under the EUPL-1.2-or-later" you will
   find references. But don’t you think that this mention should be considered
   as a future intention, commitment or guarantee provided by the licensor and
   that it should not merit a specific “actual” SPDX ID, because no later text
   exists at this time?


   - It seems that this addition is done for the GNU licenses (where the
   licence steward is the FSF – Free Software Foundation) and not for all the
   others.Is this a special treatment for GNU licenses or is SPDX policy to
   allow or apply it for all licenses, i.e. depending on the license steward
   request?

   - Has SPDX assessed the risk that this practice would multiply the
   number of identifiers with uncertain use and possibly add some confusion?

   - SPDX now considers GPL-3.0, AGPL-3.0, LGPL-3.0 etc. as "deprecated".
   Did SPDX assess the impact – which could appear as nonsense for most users?

   - Until a subsequent version, for example some GPL-4.0, exists, is it
   consistent to associate the text of the current GPL-3.0 with a specific
   SPDX identifier "GPL-3.0-or-later"?

   - ·Is it still possible for SPDX to backtrack on this subject or is it a
   definitive policy?
