Top posting a more general TEAS issue I see when looking at teas-yang-l3-te-topo

A model that introduces a new network type must define a new network type, as a presence container, as defined in RFC8345.

I assumed that this would be a flat namespace but no, it is a tree structure which means that to reference it, as happens many times with YANG when statements, you must know where in the tree it is defined.  Thus
teas-sf-aware- topo-model places it under
/network-types/te-topology
while
teas-yang-sr-te-topo places it under
/network-types/l3-unicast-topology
while
teas-l3-te-topology does both!

This seems unfortunate and likely to cause confusion, errors, over time.  Doubtless there is a logic behind the different placements but I see consistency as better.
