That is why I included the T72 and T60-1 etc. In my list as many of the other platforms had experience using these turbos and they had become something of a standard reference point. For example the T3/T4 50 trim is an old design but still is a good economical upgrade for someone who wants to go that route if they get a super deal on one, or already have one laying around from another project.
Perhaps a second listing of the obsolete and standard flange designs for reference.
Not a bad point, I'll do some research and see if I can come up with anything worthwhile.
