I'm not sure if you read my proposal, but it has a cruel irony to it. Which probably why I like it. Lol
If you ungracefully exit during danger (whether on purpose or not) you are only allowed back in to your previous mode.
While it doesn't have much effect on PvE, it can potentially put you right back where you left off with other CMDRs.
So if you pull the plug to escape a CMDR in Open, you can only rejoin Open for a limited time, you're locked out of all other modes. (Same happens in private groups, you'll be locked to that specific group)
There's a chance the CMDR might be waiting right where you vanished, or lurking in supercruise. So your choice is either risk coming back, or don't. Self inflicted punishment.
If your internet just craps out, then you're still locked to Open(or whatever), but in all likelihood, you was going to rejoin the same mode anyway.
Karma can track how often your internet dies during danger (only during danger, because it happens a lot during transitions sometimes). Too many drops in a certain time, and your mode lock timer increases.
Excessive use will lock you to solo for a certain time, with a polite message telling you your connection is too unreliable for P2P.
Again, I've heard no word from FD if this is even possible... But without tooting my own horn to much, it's the best solution which requires no input, or overly harsh punishment for unintentional disconnects.
Another idea that spawned from this, is that eventually it could be possible to preserve the entire instance, so random disconnects put you back where you was, with all ships, loot, and status intact.
Which would also sort PvE/solo combat logging, as well as with random disconnects during things like material gathering. But I imagine that's even harder to pull off.
