@yuri1969 The introduction of the Parent group makes a lot of sense.
However, I thought the idea of the Top level group was a little confusing.
Technically, the Top level group is the Root group we just do not support
navigating out of it. As an alternative, I wanted to suggest maybe changing
that part to return the nearest versioned group (if applicable) that was just
released in 1.5.0. This would be helpful in identifying which versioned flow
the component exists in.
Thoughts?
