Putting on my food safety hat...
I am glad that you have done it successfully, but it really is unsafe. The fact that the center is "done" isn't indicia of safety. The cool oven allows possibly heat resistant bacteria to wildly multiply.
The USDA specifically warns against it.
Here's what the USDA
says: "(O)vernight cooking of meat at a low temperature isn't a safe method .... so. It's not safe to cook any meat or poultry in an oven set lower than 325°F. At 200° F, meat remains in the "Danger Zone" (between 40 and 140° F) where bacteria multiply rapidly and can form toxins."
