First of all, it is Morse code, not Moore's Code, not Moore's Law.
Second, "that other thread" is this thread apparently. So, you are in the wrong place, not them.
So you can create a new thread for non-morse content and 6.12 (that you populate yourself, since I don't think you can do much without actual content), or wait for an official 6.12 thread.
That's what I got from reading the whole thing.
"Making them a thread" ("...to keep playing") was not too polite btw.
Do I like the morse code thing myself? No. Do I care about such a thread existing (or bother me)? No.
Is "since 6.10" a long time? No, but anyway. When we will be in version 8.22, they will brag about this being "since 6.10" I guess.
