I would like there be a way to differentiate from auto-resignation, resignation, and honorable resignation. I'll provide examples for each:
Auto-resignation: Player times out after 48 hours. Would be marked as "AR"
Resignation: Player resigns on their own circumstances. marked as "R"
Honorable resignation: Another player "honors" a player's resignation, because it was tactful and realistic (ie someone resigns only having 2 generators and a factory left, surrounded by total of 100 subs). This would be available once a player resigns, a star would appear next to their name, which any player still in the game can tap. marked as "HR"
This way, as more people play the game, people hopefully won't discriminate against players with a high resignation rate if they see they are honorable (like surrendering in chess).
Likewise, I hope a commendation system (like in CSGO or DOTA2) will also be put in place, so you can see how many players liked a certain player.
All of these stats would be on their security card.
