More vertical alignment options for the Columns block

[idea--list]

Is your feature request related to a problem? Please describe.
Until today columns block and related blocks make use of align-self for vertical alignment of elements in a column. However align-self is restricted to the following possibilities:
auto | flex-start | flex-end | center | baseline | stretch
This allows only very basic vertical aligment

Describe the solution you'd like
Why do not rather rely on justify-content that also allows additional settings like:
space-between | space-around | space-evenly
The only extra css that needs to be applied to the column to make justify-content work is:
display: flex; flex-direction: column;
This would open up the door for more advanced vertical alignment which are really common in any kind of design (think of media & text block for example)

Howdy @idea--list while initially I liked this idea, I wonder, considering that columns will only contain blocks that are by default aligned with an equal space-around, only the space-evenly seems to be useful for when one column becomes longer and you want the contents of other columns to be spaced evenly to the longest.

However I tested simply adding display: flex; flex-direction: column; and it changed the display of the blocks within quite a lot.
