It is not a lie. This wiki is written by Lennart who wrote Avahi, systemd and PulseAudio and is well aware of the issues and none of those are specific to Fedora which is why OpenSUSE is considering the move now as well Since you brought up FHS...

I missread the test, but did read the blog post. But you are wrong. Some distro's concider it a bug, unfortunatly a very low priority one, but still a bug. https://bugs.gentoo.org/show_bug.cgi?id=229661
I still think it be best to fix the distros and packages, to 'just forget why we split, and dump it all in /usr'. I agree however that this is the EASIER fix.
You have shown that someone bothered to file a bug report in a single distribution. This does not invalidate my claim since no action has been taken. I don't think any mainstream distribution is going to ever "fix it" by splitting /usr for the reasons stated in the wiki. The split is now considered effectively obsolete.
About this unified file system thing of moving /bin, /sbin, /lib and /lib64 into /usr/, I don't know if its a good idea or a bad idea.
What does Rob Pike, Ken Thompson, and Brian Kernighan think about this?'
The website mentions "Improved compatibility with other Unixes (in particular Solaris)", but what about BSD, HP-UX, IBM AIX, GNU, Mac OS X, and Plan 9 from Bell Labs?
The website mentions "Multiple other Linux distributions have been working in a similar direction." but does not mention any by name.
Well, the naming convention was because of hardware limitations and hence I don't the original designers have anything against this move and it wouldn't matter much now anyway because Linux is not Unix and most proprietary Unix systems except for Solaris doesn't have any significiant marketshare worth bothering about. As for other Linux distributions, read http://lwn.net/SubscriberLink/483921/704a07f93286f84e/
