I bet it is a fine design. From the early days of DD motors being the standard cheap design, my worry would be rapir costs if something went wrong with the motor. It may be a silly worry with a motor this quality, but on a belt drive table and awful lot of things can be fixed by changing a belt. Short term flutter is something I find really annoying and the deveil of old DD tables, even the much (over) liked sp-10, was when the motor went bad, you basically threw the table away.
Obviously this has different qualities and froma good designed I can see it working. However, long term speed stability and rumble are tough issues to tackle.
