Proposal: New property on Grid to suppress RowSpacing/ColumnSpacing for blank rows/columns

Summary

A new property name SuppressRowSpacingOnBlankRow="true" would skip the spacing between adjacent rows where resulting Height == 0.

Rationale

The RowSpacing is great for creating good looking layouts, but when rows are hidden (their content's Visibility=Collapsed or Height=0) and the resulting row's Height is 0, the space between all rows are no longer equal.
It would be great to be able to automatically remove the space between adjacent rows when one of them is empty.
The workaround today is to set RowSpacing="0" and use Margin="x, y" on content element. However, this is more cumbersome and forfeits the idea of the RowSpacing property.
Adding a new property for this behavior would be backwards compatible with the current behavior.
The same goes for Columns.

Scope

Must be backwards compatible with current behavior

I believe that new property is not required. It should be default behavior. I cannot imagine a case, when current behavior can be useful.
