i haven't tried compiz in maybe a little over 2 years, but it seemed pretty stable to me back then and had a lot of features. i'm sure within that time, it has been improved. is fedora seriously just ditching it because nobody is maintaining it anymore? because maybe theres just nothing to maintain. so for example suppose the linux kernel's development slows down to almost a complete halt for months. are they going to remove it? unless compiz is proving to be a problem, removing something because its orphaned is an incredibly stupid motive.
