I have a number of stack with a lot of controls in multiple nested
groups. For me, the groups are primarily for organizing objects on the
card so I can find what I am looking for as a developer. OR when I want
to move a set of related control around. In all such cases, I have never
noticed a visible difference in rendering of the cards vs card with few
groups or fewer controls in a similar number of groups.

This is just human perception. I have never timed renderings to compare.
