Scale up/ scale down

[Spangle Drongo]

I have been seeing a lot of 3d designed products that are offered in multiple scales. However something that looks good at 28mm is not appropriate at larger scales, only bigger. Similarly, there is the practice offering a full figure and a bust in the exact same pose without adjusting detail appropriate to scale. I get the lure of economies of scale reusing the same design for multiple products. What are your thoughts on this trending practice?
