There could be checks in place. Something like if the whole group has left the instance then disbands, no debuffs are given. If one person hearths out and leaves the group they get the debuff. Hearthing out and NOT leaving the group (in the case that no one has a repair mount or jeeves) only gives the debuff after 5-10 minutes.
You could get a 5 minute debuff that simply says "Not returning to your current dungeon will afflict you with Coward's Demise, preventing you from attempting more Mythic+ until tomorrow." Giving you plenty of time to find a repair and get your summon back (although who doesn't have at least the Traveller's Mammoth at this point?)
I think it could be automated, very similarly to BG deserter just a longer version of it.
The biggest issue I can see with my idea is how to handle someone being removed by the group leader since M+ is all manually formed groups. Since kicking someone from the group would technically flag them as a deserter after they got ported, there would have to be something in place to prevent 4 assholes inviting some random and then just kicking them to give them the debuff. The voting system wouldn't work as it's too easily exploitable by said 4 assholes. Not too sure how to fix that, but I don't think it would be prevalent enough to just continue ignoring the problem of people leaving keys and wasting the whole group's time/consumables.
