> my impression was that there are algorithms that work well (dont remember the name sorry), and they don't really keep track of the entire network per node, each node only has a heuristic idea of how to route packages both to local and faraway neighbors.

That doesn't change the fact that announces and extra nodes can still degrade performance. For one, it's hard to know whether a new link is better or worse than other existing links. Link conditions can also change which is very common in the kind of mesh networks folks are putting together using LoRA on antennas.

> Also, meshes need not be composed of constantly moving and changing nodes. An example of a neighborhood of houses or radio towers, where each node is semi-reliable and doesn't really move is an absolutely valid and real world use case.

Yes these are called repeater nodes in Meshcore and are already well known. Repeaters still don't have the same QoS that fiber backbones of the usual Internet have. The reason the Internet works well is because your packets are routed from your house eventually to a backbone network that helps the packet get close to its destination, and the backbone networks themselves are very top-down statically routed affairs with high capacity and QoS.

Once all of your repeaters are connected via high QoS fiber links you end up with the Internet topology we already have today.
