The term "dual licensed" that you also used in your earlier message was what threw me off because usually that term is used for software that is offered under two different licenses that the recipient of the license then can choose from (an or instead of an and). The situation with ldraw is indeed a very special one as of all 63742 software packages we ship in Debian there is not a single package that also has both CC-BY-2 and CC-BY-2. Usually, packages that are released under more than one license let the recipient choose instead of making them comply to both licenses at the same time.
An interesting legal question is, whether it's even possible to comply with both version 2 and version 4 of the CC-BY licenses at the same time but I'm sure you had legal advice on that and for me this question is only of academic but not practical interest. There are some licenses that cannot be combined with each other in that way.

That's great news, thank you! My hope is that at some point the number of 4.0-only parts is large enough such that it makes sense for me to create a part package containing only CC-BY-4.0 parts that I can then upload to the main Debian archive. Currently, due to the issues with CC-BY 2.0, ldraw still sits in the non-free archive section of Debian.

Yes, that makes a lot of sense.
Thanks a lot for your swift replies and thank you for maintaining ldraw!
