Why does the topology in version 9.5.0 look so strange?

[hzhswyz]

I used version 9.3.0 before, and the topology looks quite normal. Are there any policies adjustments?
The current topology is very deep, it looks abnormal.

version 9.5.0 General-Root topology

This means your dependencies are flat, not very distributed.
All new polices have been listed in 9.5 changelogs.
