Are there any disadvantages if we change the process execution property CHAINED_

While the impression of lag is a bad user experience, a broken chain in a wizard is a far worse user experience (they need special training to know to look for the next task in their task list). Aim to decrease the node count on the chain as much as possible, as surpassing the limit indicates that the design should be improved. But sometimes a high number of unattended nodes in unavoidable, and I personally found that it is better to increase this limit than allow the chain to be broken.
