How to escape the Linux networking stack

This is extremely tangential, but I was working on setting up some manual network namespaces recently, basically manually reproducing what docker does to fix some of its faulty assumptions regarding containers having multiple IPs and a single name causing all sort of jank, and had to freshen up on a lot of Linux virtual networking concepts (namespaces, veths, bridge networks, macvlans and various other interfaces), made a ton of fairly informal notes to make myself sufficiently familiar with the thing to set it up.

Would anyone be interested if I polished it up and maybe added a refresher on the relevant layer 2 networking needed to reason about it? It's a fair bit of work and it's a niche topic, so I'm trying to poll a bit to see if the juice is worth the squeeze.

I was actually going down rabbitholes today trying to figure out how to do a sane Docker setup where all the containers couldn't connect to each other. Your notes would be valuable at most any level of polish.
