Is equal spacing in Stacks in design tools useful?

More and more design tools are implementing some form of stacked groups that allow you to automatically set vertical spacing between the items in the group. The way this is implemented is that a single value for the spacing between all elements in the group is set and applied.

I'm questioning the validity of this. When I have a few elements stacked vertically the spacing between those elements is most likely not all going to be the same. Therefore I don't see the point of having a single value spacing in a vertical stack. Am I an exception here? Or am I missing something?

Example of a vertical stack:

• Heading
• Paragraph
• Image
• Paragraph
