"not match traits" meaning that it can't be a trigger for any civ's Golden Age? Fascinating observation.
It is way, way off the main track of techs in the second age. My guess would be that anyone who needed a wonder-triggered GA would have got it somewhere else, before building Shakes.
Either that or it's just an oversight.
EDIT: I just checked the status of last age wonders, like "Cure for Cancer" and "Longevity". Those are able to trigger a GA, though one would have to work REALLY hard not to have a GA before researching the tech and building them. Shakes is the only great wonder that is not a trigger. I'm sticking with oversight.
