I get the impression that you are not upset that the community hasn't been asked, but more that specifially you have not been asked. I already explained that asking the general public about implementation details is in general not feasible. You are a special case, because you have been a developer at some point and have experience with trueskill. However you have stopped being active and therefore missed the the developer discussions about this topic. That is unfortunate. But it is the simple reality that knowledge about who past contributors are, that could give valuable input, gets lost over time, so you can't expect people to come to you to ask you.
So in my opinion you have to decide if you want to be treated as a normal player where it is reasonable that they have no detailed knowledge about trueskill, or if you want to be treated as developer, but then you also have to participate in the relevant discussion channels to make your opinion heard.
Regarding the constructiveness of the thread, proposing to immediatly lock such threads is not a contructive thing. You can still make your case here, however I am not convinced yet why the current solution should not be used.
You made two main arguments:
This change interferes with trueskill like nothing before
True, but that doesn't say anything about if this is good or bad.
re-simulating the evolution of global ratings gets significantly harder
Debatable, but more importantly I don't see why this is relevant at all. This has no impact on the players and would really only be relevant if we needed that for some kind of testing. I have never heard anyone calling for something like this in the last years.
So please give me specific problems you see that will arise when using our modification.
