For those of you reading this now, this is not the original post. The email I had posted here was replied to, the author acknowledged his mistake, and politely asked that I take down his email. He's a well-meaning person, and I can't bash well meaning people. I've removed all references to him.
I've just unsubscribed from the GNOME Shell mailing list. Now I know I've been saying I'd do for quite some time, but the mailing list has degraded into a location for petty insults and disrespectful behavior.
Have a look at the message he was replying to, and the entire thread. This is a development mailing list. Or rather, it is in name. But it has morphed into a hotbed for rants by users who dislike the Shell, who dislike design decisions, or even who don't appreciate how much work has gone into the software (regardless of whether you like it, show some respect for the people who have put in substantial amounts of time and effort to make it in the first place). There do still exist useful and informative threads. But they have been outnumbered by whining and hissy fits.
There are tons of cases of this behavior, and it's not limited to non-developers as well. Here's one such example.
The first person who does this on hummstrumm-dev is going to be plonked faster than they can type the phrase "completely unacceptable".
