More of a trade-off between flexibility, cost, and safety. Safety features tend to constrain or eliminate various uses, which may be needed in some cases. Alternatively, safety features may be expensive (e.g., the mechanism that instantly stops a table saw when it touches flesh). In some cases, great design can improve safety at low cost while retaining utility.
