Well, conclusively %{?dist} is an optional macro which is recommended
by its lobbyists. ;-P

This is splitting-hairs. I believe the terminology in RFCs is defined
more strictly in order to avoid interoperability problems of different
implementations.  %{?dist}, being the least-significant portion of
a package EVR number, is not so important.  For all those packagers,
who use or prefer a different release versioning scheme, it is truely
optional. Whether carefully weighing the implications of using it or
not using it is required, I don't know. It doesn't add a lot of
complicated magic.
