The standard that has been discussed is her last filmed appearance for Star Trek.

I hope the Smithsonian people realize that the current appearance is not accurate to how it originally looked.
I hope everyone here realizes that the top of the primary hull has not been touched during any of the previous restorations and is still in her original glory, and should not be touched this go-round either.
Actually the engine nacelles are balanced better than you would think. The front is made from wood which is pretty dense and heavy which counter-balances the entire back which is made of rolled sheet metal. I'm not sure that the nacelle would be tearing the secondary hull apart.
