The short answer is, these are not truly logical expressions and therefore they shouldn't necessarily simplify. Of course you could adopt some arbitrary convention for such simplification, which might or might not be well-grounded in some interpretation of the licenses at issue. In the past, there was no documented uniform set of conventions and basically each package maintainer applied their own assumptions about how license expressions could be simplified, leading to general inconsistency across different packages. The general trend in Fedora that I observed over many years was that license tags were getting more specific, i.e. less "simplification" was being done (or ignoring certain licenses was occurring less). This is actually shown by the fact that the Callaway system had a "Public Domain" which was widely used in packages with license tags containing references to other licenses. So we aren't actually changing policy here. Still, the cases involving public domain dedications are fairly extreme in this regard. If we *were* to adopt some system of simplification of license expressions that's probably where we'd start.
