This is a refrain I've heard from you, Juliusz and Markus, which I actually find a bit disturbing: the desire not to really solve the problem because it's not trivially easy.   That's not the charter of this working group.   The reason we chartered this working group was _explicitly_ to study the problem carefully, to see what we needed to do to solve it well, to describe what that was, and to do it.

My experience both in doing math when I was a math student, and in doing computer science now that I'm a computer geek, is that often times a shortcut solution to a real problem winds up being harder than a good solution in the long run.   Sure, you saved a little time with that shortcut, but the long term result was that you didn't actually solve the problem, and now you have a brick that you have to fix in-place, instead of a green field where you can do what needs to be done without continuing to support the old solution.

Think about the routing problem.   We need source-specific routes.  We're extending babel to add them. Why is that? Couldn't we have just relied on happy eyeballs to eliminate the bad routes?

As for the MPvD problem, you say that you'd like to avoid the complexity, but have you actually explored what the complexity looks like?   Have you asked the Android folks and the Apple folks why they are interested in (and in some cases, already have) put support for this into their devices?

I've attached a picture of the router I'm using for my development work on this (the second, really tiny board is the serial console interface I'm using to debug).   It's got 8G of flash, 2G of RAM, a 1.2G 4-core arm64 CPU, gigabit ethernet and a fast I/O bus for both wired and wireless network interfaces.   It cost me US$24.99.   This is more than capable of supporting the complexity we are talking about, which I don't think is really that much complexity anyway.

Are you targeting a cheaper, less capable device than this?   If so, can you talk about why you think that's important for Homenet?
