They do, and it's the one thing that bothers me about their process.

The art lenses are fantastic, they do need calibration before use, and honestly it's a small price to pay, I do wonder if factory calibrating them to a multi layered sensor for end use on a bayer sensor leads to some of the need for tweaking.

That's purely layman's speculation, and I actually think the dock is great in use, and the lenses are spectacular, it's just a query.
