I'm not aware of any major distro defaulting to XFS there are a great many people using it (it has been the most reasonable choice for production filesystems >2TB as ext3 can't grow that big) and the major distros all offer XFS as install option today.
I don't disagree with the position that the end result is a "linux (distribution) problem" to the end user. But the problem is not the filesystem or the kernel. The problem is the dependence on zillions of tiny dot files (or a registry, *cough*, gconf) which absolutely can't be corrupt. Even if EXT4 provides the EXT3 behaviour there will always be opportunities for these files to become corrupted (software/hardware failure, cosmic ray, etc) and that the failure frequently results in an inability to even login is simply unacceptable. Quite arguably the file system which demonstrates its corner case behaviour more frequently is preferable since it means that developers will be more aware and more likely to address these situations.
