You know, I'm fairly sure thats not what those bugs say.
Mark says they won't fix the issue that you can't move the panel to the other side or bottom of the screen. Honestly it's down to you whether you feel this is a good or a bad thing.
The multiple monitor bug is something entirely different whereby X is putting the panel on a specific (possibly wrong) monitor due to underlying code issues. Mark has NOT said they won't fix this, in fact he's not weighed in on it. Again, YMMV on whether you believe they're doing enough about it.
But really, he hasn't said they won't fix the second bug, which is the one you're referring to, and conflating with the first bug.
