@evil_genius: it was in Chellik's office in
Specter as well
Last time it was implied to be an afterthought, a gold-plated proof-of-concept model that no one ever made anything of. This time, it's mostly there as a subtle jab at Star Trek XI (notice Garr's line there is "I have to know my enemy").
I guess you could say it's there for the same reason Riker had a pewter model of the 1701-A in his TNG quarters, with warp engines that were turned the wrong way: because we
can.
