Are native Timeloop network definitions (e.g., LegacyNetwork) still supported?

I would like to ask: are the native network definitions in timeloop still supported? Specifically, LegacyNetwork, ReductionTreeNetwork, and SimpleMulticastNetwork. I noticed that the official examples “timeloop-accelergy-exercises” do not directly use these native definitions. In the few cases where networks are included, they seem to be redefined as accelergy components, rather than using the native network types defined in the timeloop C++ code.When I include these networks in my architecture, the simulation consistently fails.
