Actually 23.976 is a hacked implementation of drop frame 24 fps because nobody has found the correct reference yet, but somebody wanted it and made a workable suggestion.

I believe that nothing serious will change in philosophy of the SMPTE code ie methodology for 47.952, 48.0, 50.0, 59.94, 60.0 will be exactly the same...

At this moment i can offer to community valid video measure signal patterns which (AFAIK) are compliant to the European nad US norms (also industrial/corporation norms ie Tektronix patterns). Patterns are verified on the Tektronix video analyser VM700 against Tektronix signal generator TG700. Normally my company used them for our product verification.
