Are we planning to add models from newer families closer to their
predecessors? I like the idea of continuing to group them by type. But,
it would inconvenience folks who are trying to find a name based on a
Family-model number. (I guess that would be a minority.)

Diamond rapids (Family 19) was added at the bottom of the file. Should
that be moved closer to its type?

Also, the /* Family 6 */ comment at the top is now misleading.

Dave had briefly suggested ordering the file based on Family, but I am
not sure if he still feels that way.
