Compiz Is Likely To Get The Boot From Fedora 17
Phoronix: Compiz Is Likely To Get The Boot From Fedora 17
While Fedora 17 has a massive amount of features to look forward to, updates to Compiz is likely not on the agenda. In the coming days, Compiz and its related packages for this compositing window manager are likely to be removed from the Fedora 17 package-list...
May be not a so good idea
KDE can use compiz alongside kwin. And some use that as far I know as Kwin on some old configuration causes trouble.
And nothing of value was lost
One can always use xcompmgr for compositing anyway.
