I would agree with that. It may come down to customer expectation. If the 4bt is mostly industrial/commercial applications, maybe they just let it shake, because the customer does not expect or demand "smooth"?
I think they do put the liquid-filled damper on marine applications. And there are the 4bts with counterbalance shafts mounted below the crank shaft. I do not know what applications got that balancing shaft.
