Thanks for the explanation. I see the reasons. We have (partially)
solved the problems in a different way. We get more robust behavior
(every node can give IPs) but in expense of more IP space used (or
just reserved). But thanks for this idea. Because it is good question
how much does really giving IP to a client counts if the node is
completely separated from the rest of the mesh.

This is true.

We also do this. Only that our customized image has dnsmasq and a
subnet allocated to it. We use image builder for this which injects
configuration into it. So you just flash and it works.

Why in client mode and not in forwarding mode?

This is a good question. How to allow at the same time non-mesh
clients to connect to the network and get IP with DHCP.
