Recent exchange that is possibly slightly related to those questions:

Basically, I believe SPDX has locked itself into a model of what an
"exception" is that is based on normative FSF doctrine built up around
FSF-authorized GPL exceptions, but which does not fully reflect how
standardized license terms actually get supplemented by other terms in
the real world with the GPL and other FOSS licenses (in some cases by
removing permissions, and in some cases where it is not actually clear
whether permissions are being removed).
