@Dunedan I made this thread primarily to see whether we could conclude that this is indeed the preferred solution in the first place, or what else. What's your take on this?
About the implementation: Your idea of recording the game starts sounds pretty good to me. The rating taking a few hours to update would be suboptimal in my opinion, though, since players might not know or notice that it happens. I guess, better late than never, but maybe we can figure out a way to make it work without such a delay?
It wasn't included in R28 because we were already way to far into the release process by the time I opened the PR. But, yes, the implementations are done, what's left is reviewing, finalising, and eventually merging it. My goal is to get everything into R29.
I'm working on it.
