+1 - Agreed, or whatever. Since switching to KDE, I've not had _any_ 
issues with user switching in KDM or SDDM. You are correct in stating 
that it doesn't work in GNOME. This is one of the reasons I use KDE 
(among many other) - my family shares a computer, and we switch users 
all day; this feature was one thing we used heavily on Windows and was a 
requirement before I introduced Fedora to them.

With all that said, I feel adding user switching to the blocker criteria 
is a logical step - this is 2015. It has worked on Windows since Windows 
Vista, circa 2003. I use it at home, and I use it at work as an 
administrator to fix problems for my users without needing to log them out.

Just because it doesn't work on GNOME isn't a valid reason not to test 
it and block on it if it is a feature that is used and depended on.
