Oh and just to make it clear once and for all, I was perfectly fine with the idea that my problems might go ignored, and in fact my running assumption all this time was that nobody knew or was interested in my particular problems. That's how mailing lists work. Sometimes you win, sometimes you lose. Half the fun of Gentoo is knowing that you're kinda on your own.
What I just wanted to talk about was an additional factor that could make the situation worse. It's entirely besides the point why I actually was ignored. Think of it like someone reporting a trivial buffer overflow in an edge use-case of a program. Fixing the issue might still not make his particular use-case work, and the fact is the buffer overflow might still be hard to take advantage of or even encounter anyway. Still needs to be reported though.
