So this is the first time I've ever seen anyone have a concern with LNSymmetry so this is exciting lol.
After I read your comment, I had this thought that I was kinda holding back, but I'll go ahead and put it out there now.
The idea behind using LNSymmetry is to then have multi-party channels. So, broadcasting an old state doesn't screw over 1 person, but rather maybe 10 or more people and those other people have a vested interest to also ensure that the newest state is the one that gets mined so even if 1 person is having some node trouble or temporary internet connectivity issues, those other people can jump in and save them not out of altruism, but to save themselves.
Now of course a multi-party channel of 10 people could contain only 2 unique individuals, and maybe that gives rise to LN node IDs being used as pseudonyms, and that does introduce a degree of trust into the system.
So I don't have much else to say other than "huh, that's interesting".

Yes, that's a more advanced version of the idea. But multi-party channels have their own problems, in particular, coordination. It's very difficult to get more than a few parties coordinated.
Which again, has limited enthusiasm for Eltoo.

The first thought that would come to mind is like a mempool for multi-party channels.
So for example we have this transaction batching service https://peachbitcoin.com/blog/group-hug/
So you would just modify that to return a multi-party channel rather than outputs to all these different addresses.
Now that doesn't work if the architecture incentivizes using nodeIDs as pseudonyms. So in that case they might coordinate on amboss.space or maybe they would coordinate over here; https://lightningnetwork.plus/ because these style of channel opens already look very similar to the coordination you need for channel factories.
Maybe channel factories work a bit like a video game guild where you send a message requesting to join and the participants of the channel factory do something similar to a channel splice to get you added in
Still though, I'm gonna go reread some whitepapers specifically how they handle the uncoorperative close mechanism.

I really like https://lightningnetwork.plus/ and have used it to bootstrap liquidity for one of my nodes. Folks should take a look if they have not seen it.
I look forward to when we can use such a pseudo social-network for channel factories and multi-party channel coordination.
